Cloudy with a chance of crab cakes

(Note: Back in November of 2013, TaxoDiary published the post “A Cloud Drifting Toward a Classification“, about the cloud formation tentatively labeled as Asperatus undulatus and the quest to achieve an official classification for it. The article below, which first appeared in the Apalachicola Times on April 8, 2015, focuses on matters of terminology concerning the same cloud, from the viewpoint of a scholar of ancient Latin language and literature. Republished by kind permission of the Apalachicola Times, which holds all rights to the article.)


The cloud’s name would be undulatus asperatus, Latin for “wave-like (and) rough.”– ALLEN GATHMAN

As locals and visitors alike will attest, all the Apalach/St. George Island folk are strong and good-looking, the children are above average, and there’s rarely a cloud in the sky.

Yet just when it seemed Ecclesiastes was right to observe there’s “nothing new under the sun” (nihil sub sole novum, as in “nihilist,” “solar,” and “novelty”), cloud buffs and cooperating scientists believe they’ve identified a previously unclassified cloud type – the first since 1951 – a variant of the undulatus class they are proposing to call undulatus asperatus, Latin for “wave-like (and) rough.” There’re lots of photos at the Cloud Appreciation Society (CAS) website at (search on asperatus then undulatus) and a compilation of videos on YouTube (search “undulatus asperatus compilation”).

Gavin Pretor-Pinney, founder of the CAS, resourcefully tapped into the mother tongue for the name of the cloud formation, which he and Graeme Anderson, a meteorologist assisting his research, hope to have officially recognized by the United Nations World Meteorological Organization (WMO) this year or next. Undulatus, like English “UNDulate,” means to “move like ocean waves,” from the noun unda/“wave.” That same root word gives us “redUNDant,” a synonym of “repetitive,” which, once you know this bit of Latin, evokes an image of waves breaking again and again (re-), REpeatedly, against the shore and sending the sand crabs skittering. The root of asperatus appears in “exASPERate,” literally “to roughen” but commonly (as when your spouse describes your mannerisms!) meaning “to irritate, annoy, anger.” You might also know the noun “ASPERity,” meaning roughness – of touch, of climate, or of a person’s behavior. Vergil in his first century B.C. epic poem the Aeneid used the phrase asperat undas of a wintry storm at sea that “makes the waves rough.”

The Latin word for clouds in general is nubes, and the Romans called the centaurs nubigenae, “cloud-born” (from gen-, “to beget,” as in “GENerate” and “proGENitor”), since the murderous Ixion had seduced a cloud-image of the goddess Hera, enGENdering a deformed son Centauros, who later mated with a group of mares and sired those mythic man-horse critters! A rain-cloud specifically is a nimbus, which gives us “cumuloNIMBUS” for those menacing, heaped up, towering clouds that can signal a coming rainstorm or hail: Latincumulus is a “heap” and to “acCUMULate” is to pile things up–like the little mounds of sand those tiny sand crabs often kick up round their holes along the St. George shoreline. “Cumulonimbus” was originally called “Cloud Nine” in the inaugural edition of the WMO’s International Cloud Atlas, published in 1896; that work’s title likely influenced the name of a series of piano compositions by Yoko Ono’s first husband, Toshi Ichiyanagi, whose music in turn inspired the title of David Mitchell’s sci-fi novel “Cloud Atlas” and its 2012 film adaptation.

Here’s wishing you a euphoric, not rainy, Cloud Nine day, and may all yournubes be lined with silver (argentum, chemical symbol AG). As for me, I’m heading down to Water Street in quest of crab cakes, and as I slather them with remoulade I’ll try not to think of their crustacean brethren frolicking on the cloudless beaches of St. George Island.

By Rick LaFleur

Rick LaFleur is retired from 40 years of teaching Latin language and literature at the University of Georgia, which during his tenure there came to have the largest Latin enrollment of all of the nation’s colleges and universities; he is not quite sure whether he loves Latin or Apalachicola more.

To Cap or Not to Cap?

Every once in a while, the issue of capitalization in taxonomies and thesauri pops up. Some of us in taxonomy land believe that it does make a difference what capitalization (versus lower case) style you use. We just don’t necessarily agree what that style should be.

The National Standards Organization Institute (NISO) standard for controlled vocabularies (ANSI/NISO Z39.19, Guidelines for the Construction, Format, and Management of Monolingual Controlled Vocabularies), which was last revised in 2005 and reaffirmed in 2010, has this to say on the subject, on page 34:

It is recommended that predominantly lowercase characters be used for terms in controlled vocabularies… Capitals should be used only for the initial letter(s) of proper names, trade names, and for those components of taxonomic names, such as genus, which are conventionally capitalized. Capitals should be used for all the letters of initialisms or where featured in unusual positions in product or corporate names. Because lowercase letters can occur in unusual positions in proper names, using a combination of capitals and lowercase letters in controlled vocabularies indicates to the user the correct orthography of a term in natural language and serves to distinguish common nouns from similar proper names. 

Example 57: Capitalization of proper and trade names

[A note about “should”: Per ANSI/NISO Z39.19, page 2, “The conventions used in this Standard to indicate the force of recommendations are: must (required for meeting the Standard), should (recommended), and may (optional). The Standard also uses the conventions must not (not allowed in order to be in compliance with the Standard) and should not (not recommended).” So the NISO standard recommends the practice above, but does not insist on it.]

[Another note: A reconsideration/revision of Z39.19 is due soon.]

Most of this makes sense to me. It’s certainly much better than the solid caps default of early machine-readable taxonomies and thesauri. From what I understand, they were completely capitalized because of technological limitations and space-saving considerations. Have you ever tried to browse the printed records of those vocabularies? They’re horribly difficult to read.

At the same time, the readability issue is what makes me object to Z39.19’s recommendation. Specifically, I have problems with the terms that begin with lowercase letters. They sort of merge with the line above, rather than clearly being separate terms. They don’t have the visual boundaries that capitalization can provide.

I do appreciate the rationale of Z39.19 that “using a combination of capitals and lowercase letters in controlled vocabularies indicates to the user the correct orthography of a term in natural language.” And I know fellow taxonomists who strongly agree with the lowercase-unless-it’s-a-proper-noun approach. For a general controlled vocabulary that serves as a reference for how terms appear in natural language, that dictionary-ish approach kind of makes sense.

My take on that, though, as far as taxonomies and hierarchical thesauri are concerned, is that taxonomies and their kin are more like outlines than like dictionaries, and outline items are capitalized for clarity, to indicate where new items start. Moreover, most traditional dictionaries have the visual benefit (for our purposes) of tiny text filling up the distance between terms, whereas in hierarchical taxonomy displays (which are generally the most useful views), the terms appear on consecutive lines. And indents can confuse things even more if terms are lowercase; the narrower terms look like runover lines.

Taxonomist Heather Hedden has written a blog post on the subject of capitalization in taxonomies. She views initial capitalization of terms as analogous with capitalization style in headings:

A “taxonomy” implies a hierarchical classification or categorization of concepts. When we think of categories we think of labels or headings with subcategories. Headings in general tend to have initial capitalization or title capitalization. Thus, if it’s a strictly hierarchical taxonomy, where all terms are interconnected into a single hierarchy or a limited number of hierarchies, then it will more likely have initial capitalization or title capitalization. Such capitalization is particularly common on the relatively smaller/less detailed taxonomies that are proliferating on websites, intranets, and content management systems. It fits in with the web design style of capitalization on headings and categories.

As Heather points out, initial capitalization is a fairly common practice, despite Z39.19. I think she’s referring mostly to initial (letter) capitalization of the first word; I haven’t seen that Title Style is common at all. (In fact, I don’t remember seeing it at all in a taxonomy.)

I have seen modern taxonomies and thesauri that have solid (every letter) capitalization on the just on the top level, to indicate major categories. These are usually just category designations, rather than indexing terms. Heather comments: “A good application of the mixed capitalization style is if the top level terms were not actually to be used in indexing/tagging but are really just categories/groupings of the actual index terms, which in-turn are arranged hierarchically underneath.”

Ultimately, it’s up to the taxonomy owners to determine what style to use. (And might I remind you, a reconsideration of Z39.19 is due soon.) The main factors to consider are readability, clarity, and usability.

Taxonomy Blogs – The Big Picture

May 4, 2015  
Posted in Access Insights, Featured, Taxonomy

dreamstime_m_20414095© Icefields | Dreamstime.comBlog Icons Photo

We who blog on TaxoDiary know that it’s not the only blog that has to do with taxonomies and such. There are a few others out in cyberspace, and each has its own character. Let’s take a look at some of them, starting with what we know best.


You already must know something about TaxoDiary; you’re reading it right now. Maybe you haven’t read the description, though, which might provide some new insight:

TaxoDiary covers all types of knowledge organization systems (KOS), and related subjects. It is designed to provide the taxonomist, indexing and content professional with news and opinions about metatagging, and the application of KOS to increase findability of information objects within or across large collections of information, structured in databases, or unstructured in content repositories using controlled vocabularies. These activities are not unique to a single country or language, but rather shared and active globally.  It is part of our effort to keep abreast with the constantly changing field and to provide us information for research and used in consideration for the creation of new products and services. We will provide a regular stream of information about these topics and hope to share with you an informative and lively forum for discussion worldwide.

TaxoDiary is somewhat unique in that new posts appear each weekday.

The Accidental Taxonomist

The Accidental Taxonomist blog is written by Heather Hedden, perhaps best known for her book The Accidental Taxonomist. In the first post, in 2011, Heather gave a preview that turned out to hold true for the subsequent years:

Where will my new blog post ideas come from?

As a consultant, I am constantly engaging in new taxonomy projects with new experiences, new lessons to be learned, and new insights into the field. My client names should be kept confidential, so writing complete case studies may not be feasible, but the short informal nature of a blog post is quite appropriate to share some thoughts.

I also attend a number of conferences during the course of a year, and there are always new ideas coming out of these events. Some of my blog posts will be based on my own presentation topics, but not a repeat of the slide bullets, though. Instead I will provide some commentary about the presentation topic, such as why it is significant, timely, of interest, or what my concerns are. Other posts will be my observations an ideas gleaned form what others presented.

I may decide to revisit a topic in my book for a blog post. But I could also explore some new direction of topics related to taxonomies, such as content management, information architecture, search, or digital asset management.

The Accidental Taxonomist blog averages about one very substantial post per month.

The Taxonomy Blog

From the name, it’s fairly clear what this blog is about. While no longer active, it is still online (at least for the time being) and has some very useful posts on taxonomy philosophy and methodology. It was formerly maintained by taxonomist Marlene Rockmore, with help from Heather Hedden. To give you an idea of the approach, here’s how Marlene describes herself:

I call myself the “Classy Taxonomist.” I help organizing concepts which leads to clear thinking, better analysis, and results. I use taxonomies to help you figure out how to communicate by sorting meaning into buckets. Once you have buckets, you can then build interfaces and processes more efficiently. Big Bird once said “One of these things is not like the other.” I’ve been doing this since 1986. Clients include Harvard Business School, Digital, 6.2Million Tax Override, Conoco Philips, Boston College, O’Reilly, and Google.

Earley & Associates blog

Earley & Associates is a consulting organization headed by prominent knowledge management expert Seth Earley. Their blog covers a wide range of information management topics, but the posts indexed with “Taxonomy” far outnumber the posts indexed with other topics. The website has a page of research suggestions, one of which is to “check out our blog” if “you want to get a pulse on what is new and hot.”

Taxonomy Watch

This blog had the tagline “A weblog about taxonomies and their application in organizing digital content. Also includes related topics such as controlled vocabulary, thesauri, topic maps, ontologies and semantic technologies.” It was maintained by Gwen Harris, and discontinued in 2012. Gwen wrote in 2012 that the blog would be taken down soon, but as I write this, it’s still there. There’s a lot of good stuff there; take a look.

Click Three Times?

April 27, 2015  
Posted in Access Insights, Featured, Taxonomy


Photo by GorillaSushi,, CC BY-SA 2.0

Every now and then, we hear or read the advice that taxonomies should be no more than three levels deep. The reason given is what’s commonly known in the web design world as the three-click rule. Supposedly, users do not have the patience to find information on a website using any more than three clicks of a mouse. Ergo, navigation hierarchies and similar structures are expected to honor this limitation by keeping the entire pool at kiddie depth.

A quick web search shows that the rule has received wide credence and distribution. Is it valid, though? And does it apply to taxonomies?

There have been doubters. In 2009, usability consultant David Hamill wrote a strong (albeit gruesome) statement about the rule:

The 3-click rule is the Freddy Krueger of web design advice. You think it’s finally dead and then it comes back and starts slashing up sensible debate about usable design. I’m hoping to convince you to stop talking about the 3-click rule. I don’t mean substituting it with the 4-click rule or the 5-click rule. You should stop counting clicks as a measure of usability altogether. [Hamill’s emphasis]

Hamill continues:

In 2003, Joshua Porter of User Interface Engineering wrote an article that should have killed the 3-click rule for good. He found that the number of clicks affects neither task completion nor user satisfaction. …

Once the 3-click rule had been disproved, you might expect click counting to fall out of fashion. But alas it hasn’t.

Joshua Porter’s article, Testing the Three-Click Rule, was originally published in April 2003. In it, Porter explains the research that his team conducted, and the findings that they uncovered. One of the more basic findings was that “Hardly anybody gave up after three clicks.” People were willing to click as many as 25 times to find what they were looking for. He concluded,

We can’t be overly critical of a rule that has the effect of helping designers keep their focus on users and their needs. However, the Three-Click Rule does not focus on the real problem. The number of clicks isn’t what’s important to users, but whether or not they’re successful at finding what they’re seeking.

Interface designer Ally Reeves elaborates on the findings, with an interpretation that argues for logical, intuitive, and moderately deep hierarchical structure:

What if your navigation structure gracefully leads users beyond 3 clicks into a 5 click navigation that gets them to the right place? Or more than 5 clicks?

Never fear. Research shows that if the progressive revelation of information takes the user down a path towards refinement that feels like progress and gets them where they need to be, they will give you up to twelve clicks before turning grumpy. Yes, twelve.

And that’s about the maximum depth for a typical science or humanities taxonomy or thesaurus. And that’s about the depth that’s needed in order to offer the degree of granularity or specificity that researchers require.

So if there’s no solid basis for the three-clicks rule, where did it come from in the first place? The answer surfaced in a blog post last June by Martin White, who revealed that Dr. Peter Cochrane, an Internet technology pioneer, was the originator. White explains:

The three clicks rule was proposed by Peter around 1998/1999 and had nothing whatsoever to do with navigation structure optimization. Peter was a telecoms engineer and his concern was over bandwidth latency as the use of the Internet increased but was still largely running over copper and not optical fibre. It was typically taking 15-20 seconds for a page to load in response to a click and so three clicks might take a minute to complete. …

His concern was that unless there was a significant network capacity upgrade world wide the delay for a user even needing as few as three clicks would be such that they would give up the task, and that as a result the Web might never fulfil its potential. He wrote this around 1998:

“Who would like a three click, one second, no handbook world? Drill down to anything you want in three clicks of a mouse, and it appears on your screen in under a second! No need to read a handbook, no training – just the application of intuition – an obvious and easy to use interface for everyone. The only prospect of realising this dream relies on ‘end-to-end’ optical fibre and significant improvements in network and computer protocols, interfaces and software.”

This is just to put the origin of the three clicks rule on the current record and hopefully to stop people wasting their time trying to prove or disprove a half-remembered proposition.

So don’t think that you have to limit your taxonomy or thesaurus to three or perhaps four levels. People are willing to dig deeper, as long as they have reason to think they’re getting somewhere.

Alice Redmond-Neal Crosses the 30,000-Abstract Threshold for IFEBP and Access Innovations, Inc.

April 20, 2015  
Posted in Access Insights, Featured, Taxonomy

Access Innovations, Inc. is proud to announce that one of its devoted staff members has crossed a large indexing and abstracting milestone.

Chief taxonomist Alice Redmond-Neal has worked on over 50 projects for Access Innovations, from the most general to the most specific, but none has she worked on more closely than her long-standing work for the International Foundation of Employee Benefit Plans (IFEBP). For years, Alice has written abstracts for and indexed their articles, and has now crossed over the 30,000-abstract mark. Regarding this feat, Margie Hlava, President of Access Innovations, stated, “Alice has long proven herself to be a valued employee, a skilled taxonomist, and most importantly, a great friend to the company. From everyone at Access Innovations, I want to congratulate her and thank her for her dedicated work.”

Alice remarks, “I am very honored to have worked for EB for so long on this project. It’s important to note that many people have worked on this project, but their trust in the quality of my work and the strong service that Access Innovations offers is well noted. It doesn’t hurt that we have built such a warm and friendly relationship with the client, as well!”

Since 1986, Access Innovations has been producing the Employee Benefits INFOSOURCE database, which provides a centralized resource for timely, comprehensive information about all facets of employee benefit plans. Access Innovations indexes and abstracts articles from more than 350 journals and newsletters and, in the nearly 30 years since the project began, Access Innovations has produced over 100,000 abstracts; Alice herself has been an integral part of nearly a third of that work.

Access Innovations looks forward to the continued growth of the INFOSOURCE database and waits eagerly as Alice inches toward the next milestone.

A Short Roundup of Recent Taxonomy Books

April 13, 2015  
Posted in Access Insights, Featured, reference, Taxonomy

© Nasir1164 | – 3d People Around Books Photo

Over the past couple of decades, the field of knowledge organization systems (such as taxonomies and thesauri) has matured. This maturation has led KOS experts to write books that consolidate and share the theories, insights, and techniques that have emerged. Below is a roundup of some of the more recent books in the area of taxonomies and related knowledge organization systems.

The Taxobook

One of the most recent books, published as a trio of monographs, is The Taxobook, written by Access Innovations President Marjorie Hlava and published by Morgan & Claypool Publishers. TaxoDiary recently had a blog post about The Taxobook. We’ll reiterate the summary:

Volume 1, The Taxobook: History, Theories, and Concepts of Knowledge Organization, introduces the foundations of classification, covering theories from the ancient Greek philosophers to modern thinkers. This volume also includes a glossary that covers all three volumes.

Volume 2, The Taxobook: Principles and Practices of Taxonomy Construction, outlines the basic principles of creation and maintenance of taxonomies and thesauri. It also provides step-by-step instructions for building a taxonomy or thesaurus and discusses the various ways to get started on a taxonomy construction project.

Volume 3, The Taxobook: Applications, Implementation, and Integration in Search, covers putting taxonomies into use in as many ways as possible to maximize retrieval for users.

The Accidental Taxonomist

This book, by well-known taxonomy expert Heather Hedden, was published by Information Today Inc. in 2010. Here’s the publisher’s summary:

The Accidental Taxonomist is the most comprehensive guide available to the art and science of building information taxonomies. Heather Hedden—one of today’s leading writers, instructors, and consultants on indexing and taxonomy topics—walks readers through the process, displaying her trademark ability to present highly technical information in straightforward, comprehensible English.

Drawing on numerous real-world examples, Hedden explains how to create terms and relationships, select taxonomy management software, design taxonomies for human versus automated indexing, manage enterprise taxonomy projects, and adapt taxonomies to various user interfaces. The result is a practical and essential guide for information professionals who need to effectively create or manage taxonomies, controlled vocabularies, and thesauri. 

Introduction to Controlled Vocabularies: Terminologies for Art, Architecture, and Other Cultural Works 

This book, originally published in 2010 by J. Paul Getty and revised in 2013, focuses on controlled vocabularies for the world of museums and cultural studies. Author Patricia Harpring is managing editor of the Vocabulary Program at the Getty Research Institute, which maintains some highly respected thesauri and other controlled vocabularies, including the Art & Architecture Thesaurus (AAT), the Union List of Artist Names (ULAN), the Getty Thesaurus of Geographic Names (TGN), and the Cultural Objects Name Authority (CONA). Co-author Murtha Baca is Head of Digital Art History at the Getty Research Institute. Here’s the Institute’s description of the 2013 revision:

This primer on the characteristics, scope, uses, and methods for building and maintaining controlled vocabularies for art and cultural materials explains how vocabularies should be integrated in cataloging systems; utilized for indexing and retrieval; and structured to group synonyms and arrange concepts into categories.

The updated edition reflects recent developments in the field, including new national and international standards, current trends such as Linked Open Data, and revisions to the Getty vocabularies. The glossary and bibliography have also been updated.

Structures for Organizing Knowledge: Exploring Taxonomies, Ontologies, and Other Schema

This book, published in 2010 by Neal-Schuman Publishers, was written by June Abbas, whose research focuses on the development of user-centered digital libraries, institutional repositories, and knowledge organization structures. In the Preface, she outlines the three major sections of the book:

Traditional Structures for Organizing Knowledge—Part I looks at structures used in libraries, such as MARC records, subject headings, and classification schemes, as well as traditional structures that may not be as familiar, such as those from natural science. The historical  contributions to the organization of knowledge from fields such as library and information science, philosophy, natural science, and cognitive science are examined. Exemplars of how the structures have remained the same and/or have been adapted for use in the digital environment are also included in this section.

Personal Structures for Organizing Knowledge are the focus of Part II. These are systems developed by individuals in both home- and work-related contexts. Several research streams from library and information science (knowledge organization and human information behavior) and human–computer interaction (personal information management) are introduced, and research in each area of personal knowledge structures is explored.

Socially-Constructed Structures for Organizing Knowledge, or those that are beginning to merge as the result of individual and collaborative uses of social bookmarking and social cataloging Web 2.0 sites, are examined in Part III. Research focused on these new environments is becoming more prevalent and providing information professionals with a glimpse into how people organize their own collections. 


In 2008, the American Library Association published the first edition of this book by Marcia Lei Zeng and Jian Qin, two experts in the field of knowledge organization systems and in the metadata connected with those systems. The second edition is scheduled to be released in 2016. Here’s the ALA’s description of the new edition:

Metadata remains the solution for describing the explosively growing, complex world of digital information, and continues to be of paramount importance for information professionals. Providing a solid grounding in the variety and interrelationships among different metadata types, Zeng and Qin’s thorough revision of their benchmark text offers a comprehensive look at the metadata schemas that exist in the world of library and information science and beyond, as well as the contexts in which they operate. Cementing its value as both an LIS text and a handy reference for professionals already in the field, this book

Lays out the fundamentals of metadata, including principles of metadata, structures of metadata vocabularies, and metadata descriptions

Surveys metadata standards and their applications in distinct domains and for various communities of metadata practice

Examines metadata building blocks, from modeling to defining properties, and from designing application profiles to implementing value vocabularies

Describes important concepts as resource identification, metadata as linked data, consumption of metadata, interoperability, and quality measurement

Offers an updated glossary to help readers navigate metadata’s complex terms in easy-to-understand definitions

An online resource of web extras, packed with exercises, quizzes, and links to additional materials, completes this definitive primer on metadata.

Organising Knowledge: Taxonomies, Knowledge and Organisational Effectiveness

This book, by knowledge management consultant Patrick Lambe, was published by Chandos Knowledge Management in 2007. In the book’s introduction, Lambe offers an overview:

In the first half of this book we’ll challenge a number of assumptions about taxonomies and the work of taxonomy building, and relate this work to organization effectiveness and knowledge management.…

In the second half of this book, we take a more practical approach and guide you through the steps involved in a ‘typical’ taxonomy project. Here we challenge the assumption that taxonomy development can be done in the abstract, by a consultant, sitting apart from the information and knowledge world of the organisation it is intended for. Very few taxonomies can be developed in that distant, unengaged way.…

To close, in Chapter 10 we take a forward look at issues and challenges on the horizon for knowledge managers. What do the semantic web, folksonomies, ontologies and social tagging mean for taxonomy work? Will we need taxonomies at all?

Those of us involved with TaxoDiary believe that taxonomies, thesauri, and other controlled vocabularies will continue to be relevant to knowledge management and information retrieval. And we look forward to seeing new insights and approaches, and new books.

Using Taxonomy to Save a Butterfly

April 6, 2015  
Posted in Access Insights, Featured, Taxonomy

The monarch butterfly is a beautiful sight, whether it’s fluttering through a garden or resting on a flower. Understandably admired, it’s the state insect of Alabama, Idaho, Illinois, Minnesota, and Texas. It’s also the state butterfly of Vermont and West Virginia.

Unfortunately, the monarch butterfly population has been dropping drastically over the past decades. The situation is explained in a recent article authored jointly by Daniel M. Ashe, Director, U.S. Fish and Wildlife Service, and Collin O’Mara, CEO, National Wildlife Federation:

As recently as 1996, the estimated monarch population wintering in Mexico was more than one billion butterflies, turning forests into seas of orange and black. Last year, however, the wintering population numbered only about 56 million butterflies, gathered on fewer than three acres of forest.

Monarch butterflies, as well as other butterfly species, bees, birds and bats help move pollen from one plant to another, fertilizing flowers and making it possible for plants to produce seeds, berries, fruits and nuts that feed people and wildlife. More than a third of the food that we eat requires pollinators to grow. Yet like the monarch, many of these pollinators are declining, with habitat loss, pesticides and climate change all contributing to their struggles.

We need to know more about exactly why monarch butterflies are disappearing. But we don’t need to wait to take the actions that scientists tell us are necessary to redirect the monarch’s future skyward.

What can we do? Well, for one thing, we can plant milkweed.

Many of us in North America and elsewhere know that monarch butterfly larvae need to feed on milkweed (genus Asclepias) in order to achieve their transformation into winged butterflies. (As a matter of fact, so do the larvae of the monarch butterfly’s closest relatives, the other “milkweed butterflies” of the genus Danaus.) The monarch’s fate hinges on the available supply of milkweed in its natural geographic distribution. Various factors, including well-intentioned weeding, have caused that milkweed supply to dwindle.

Practically anyone can grow a successful patch of milkweed, as long as the right kind of milkweed is chosen and the right conditions are provided. Texas Butterfly Ranch’s aptly named “Got Milkweed?” planting guide offers this caution:

Those of us who have attempted cultivation of native milkweeds from seed in our home gardens have often met frustration and failure. The very traits that make native plants so hardy also often make them extremely particular about their soil, drainage, moisture and available light. As George Cates, chief seed wrangler at Native American Seed Co. in Junction, Texas told me: “These milkweeds have a mind of their own.”

Another reason to plant a species that’s native to your geographic location is that the monarch migration is largely dependent on the timing of milkweed blooms. Tropical milkweed, in particular, when grown outside of extreme southern areas of Texas and Florida, can throw off migration patterns, leading to disease and other problems. Ironically, gardeners wanting to help the monarchs have been planting the more readily available non-native milkweeds. As explained in an article in the February 2015 issue of the Proceedings of the Royal Society B:

Each autumn, monarchs migrate from breeding grounds in the eastern US and Canada to wintering sites in central Mexico. However, some monarchs have become non-migratory and breed year-round on exotic milkweed in the southern US. We used field sampling, citizen science data and experimental inoculations to quantify infection prevalence and parasite virulence among migratory and sedentary populations. Infection prevalence was markedly higher among sedentary monarchs compared with migratory monarchs, indicating that diminished migration increases infection risk. Virulence differed among parasite strains but was similar between migratory and sedentary populations, potentially owing to high gene flow or insufficient time for evolutionary divergence. More broadly, our findings suggest that human activities that alter animal migrations can influence pathogen dynamics, with implications for wildlife conservation and future disease risks.

Gardens planted to accommodate monarch migration are sometimes referred to as waystations. In an article on butterfly gardening for monarchs (where the ubiquitous and irresistible “Got Milkweed?” pops up again), Carole Sevilla Brown recommends, “Plant a Monarch Waystation. Go to the USDA Plants database to determine which species of Asclepius are appropriate for your garden.” Chances are that the species appropriate for your garden is/are what’s native to your area. (Essentially, that’s what the USDA Database shows.)

Ah, species. A look at the Encyclopedia of Life’s Asclepias taxonomies shows the complexity. There are dozens of Asclepias species, viewable by traditional biological taxonomy structure (the NCBI Taxonomy or the Integrated Taxonomic Information System), as well as by Extant and Habitat resource, as well as a few other slice-and-dice approaches. It’s apparent from these resources that there are milkweeds for all kinds of different growing conditions, from wetlands to scrubland.

Wherever you live, you can use one of the various online taxonomic resources, or a database that’s correlated with a detailed taxonomy, to determine what kinds of milkweed to grow.

Got milkweed? No? Use a taxonomy, and get milkweed!
