For anyone unfamilar with these fascinating, important, and and endangered aridland wetlands, a recent web project focusing on those of New Mexico provides a very nice introduction - see Christina Selby's Las Cénegas storymap project (will open in a new tab).
Hendrickson's initial work on them in the 1980s was summarized in the now widely cited paper:
Hendrickson, Dean A., and W.L. Minckley. 1985. “Ciénegas-Vanishing Climax Communities of the American Southwest.” Desert Plants 6 (3): 130–176. https://doi.org/10/gg5s3w.
and he more recently collaborated with other fans of ciénegas to provide a geospatial database on those of the arid areas of the southwestern US and northwestern México (Hendrickson, Dean A., and Thomas A. Minckley. 2018. “Aridland Ciénegas of Western North America”). It was publicly available for exploration and download at https://fusiontables.google.com/DataSource?, but unfortunately, since Fusion tables were recently deprecated by Google, the data are now available to anyone only via emailed requests. A new collaboration with collaborators at US Geological Survey will again (in 2021) make this database openly available to the public. However, our extensive North American Ciénegas bibliography remains openly accessible. If you are a researcher working on ciénegas, or notice resources that we have missed, please let us know.
The amazing valley of Cuatrociénegas, in the Chihuahuan Desert of central Coahuila, México, has long been a focus of Hendrickson's efforts, and is a large part of the total citations in the bibliographic database as it has been extensively researched. This small desert valley harbors an amazing diversity of endemic species, mostly aquatic, but also terrestrial. Beginning in the early 1990's Hendrickson has had projects there studying the fishes and other organisms, and for many years ran a small research station there (with support from Desert Fishes Council). The objective was to work with the local community to facilitate all kinds of research relevant to conservation of this amazing place. Along the way, with local support, Hendrickson organized several meetings of interested researchers in Cuatrociénegas with as many as 300 participants, and carried out many projects with the support of the local CONANP office. Unfortunately, diverse factors caused the research station to be closed, but the interest persists and we hope one day to again secure the resources to renew this effort. We continue to maintain our contacts with our many good friends and supporters in the area.docid=1n9Z5nJ7BXY0TLBbGjFYzFcRooMWCWK_AQDQVAV24#rows:id=1.
