Another successful field season for the Research & Conservation department

The changing of the seasons is marked in the Research & Conservation department not only by the fact that the days are getting noticeably shorter, but by the fact that we have all returned indoors for the year. The growing and collecting season has dwindled for our botanists and mycologists, and we are now busy processing and analyzing the fruits of our summer labors.

Celebrate Endangered Species Day

Denver Botanic Gardens staff and volunteers conduct annual monitoring of the Colorado hookless cactus

Did you know that more than 1350 species in the US are protected under the Endangered Species Act? A whopping 792 (57%) of them are plants. Today is the sixth annual Endangered Species Day, a day to celebrate our endangered species. There are 29 species in Colorado listed as Threatened or Endangered under the Endangered Species Act.

Denver Botanic Gardens co-hosts the Center for Plant Conservation Annual Meeting

Last week we were honored to co-host the Center for Plant Conservation Annual Meeting along with the National Center for Genetic Resources Preservation (NCGRP) in Fort Collins.  Conservation professionals from more than 20 botanic gardens, federal agencies, and organizations across the country gathered in Colorado for a four-day conference to celebrate our efforts to conserve our nation’s rarest plants.

The Center for Plant Conservation (CPC) is a consortium of botanic gardens dedicated to protecting our nation’s vanishing flora.  Denver Botanic Gardens was one of the founding partners of the CPC 27 years ago (1984).  We have been actively involved in seed collection and other conservation efforts in collaboration with the CPC ever since.

Water-Smart Gardening: Appearances Can Be Deceiving

If a yard or garden looks like it has been transplanted from the desert, does that make it a “water-smart garden?”  One might make the assumption that the plants do not need much supplemental water and, therefore, the homeowner is being frugal with his or her water application.  This may actually be an incorrect notion.

Interns pair up with research team to ensure the future of Penstemon harringtonii

To a Colorado non-native, the the gypsum dust blowing through Eagle County could easily obscure the beautiful wildflowers growing amongst the mountainous anthills and dry lakebeds. Penstemon harringtonii is a rare,  showy purple and blue flower limited to the sagebrush steppe in Colorado and limited in number as well. A changing habitat and the ever-so-ambitious human dweller threaten this endemic species.

This year, the horticulture interns joined up with the Gardens research team on their 14-year field study to ensure the future of this plant.

What threatens the Colorado hookless cactus?

Sclerocactus glaucus habitat

Sclerocactus glaucus habitat

What threatens Sclerocactus glaucus (see a video showing some of the causes)? Installation and maintenance of huge pipelines that move oil and gas from the well pads miles and miles to the collection facilities; roads; browsing and trampling from livestock; weeds; and people who collect them from the wild to name a few. Why are we doing something about it? Just look at the beautiful landscape and plant community. Do you want to lose that? Neither do we.
