Washington Jacob\u2019s Ladder has existed on the Columbia Basin for thousands of years. Now, scientists say it\u2019s at risk of extinction.<\/p>\n
The Center for Biological Diversity has petitioned the U.S. Fish and Wildlife Service to protect the plant under the Endangered Species Act. <\/p>\n
Mark Darrach, a researcher at the University of Washington Burke Museum, principal at Corydalis Consulting and contract researcher for the Center, and Gwendolyn McManus, a staff scientist at the Center\u2019s endangered species program who has petitioned for around five different species this year, authored the petition.<\/p>\n
If the plant is granted protection, it will \u201cunlock more funding for its protection, more research \u2013 just kind of get more attention on it,\u201d McManus said. \u201cIt can also help raise awareness for landowners who have those plants on their land, and in some cases can help landowners get additional help if they want to conserve the plants.\u201d<\/p>\n
There are currently 892 flowering plants in the United States classified as endangered by the Fish and Wildlife Service.<\/p>\n
The effort to classify the plant as endangered began when Darrach surveyed populations of the plant, something he and a field partner do with a different plant each year. Together, they assess plants with declining populations to determine whether they believe a petition is warranted.<\/p>\n
\u201cA lot of them haven\u2019t been visited for decades, sometimes many decades,\u201d he said.<\/p>\n
Even before the survey, Darrach was aware that Washington Jacob\u2019s Ladder was \u201con its way out.\u201d<\/p>\n
\u201cWe knew it was rare,\u201d he said. \u201cIt\u2019s got a very limited profile as far as its habitat preferences go. It requires moisture, which in central Washington, north of I-90, is pretty limited.\u201d<\/p>\n
A decline in water sources is a significant contributor to the plant\u2019s rarity.<\/p>\n
\u201cThe biggest factor overall, I think, has been the loss of groundwater, because there\u2019s so much groundwater that\u2019s being pumped out of that area for irrigation,\u201d Darrach said.<\/p>\n
Washington Jacob\u2019s Ladder needs bare soil to grow. Historically, bare soil in central Washington has been a function of floodplains, areas of land near flowing bodies of water that regularly flood. Recently, however, streams in the area have been straightened for agricultural purposes. <\/p>\n
\u201cSo, during spring floods that might occur, or particularly large rainstorms that might occur on occasion, those floodplains really aren\u2019t there anymore,\u201d Darrach said.<\/p>\n
Without the bare soil, Washington Jacob\u2019s Ladder has difficulty reproducing. Because of this, many populations consist mostly of very old \u201czombie plants,\u201d as Darrach called them.<\/p>\n
\u201cMost of the populations are only mature adults, and there\u2019s very little seedling recruitment,\u201d McManus said. \u201cThere are very few young plants.\u201d<\/p>\n
Without younger plants, most populations of Washington Jacob\u2019s Ladder cannot survive into the future.<\/p>\n
\u201cThey\u2019re just going to live out their lifespan, and then the population disappears,\u201d Darrach said. \u201cThere\u2019s only three, possibly four populations that are still viable over a fairly long-term period, we think.\u201d<\/p>\n
Fires are also a threat to the plant, though Darrach said they haven\u2019t had much of an impact yet.<\/p>\n
\u201cThe heat from a wildfire could potentially destroy the plants,\u201d he said. \u201cWe didn\u2019t really have a very good sense of how much risk the plants are at as far as fire goes, because we didn\u2019t really see any wildfire evidence. But it\u2019s just a matter of time until some of them burn up.\u201d<\/p>\n
Darrach said despite the low number of plants, Washington Jacob\u2019s Ladder is an important part of the central Washington ecosystem.<\/p>\n
\u201cIt\u2019s a plant that has real importance to pollinators \u2013 the bees, our native pollinators,\u201d Darrach said. \u201cAnd it\u2019s in full bloom at a time when the blooms of other plants in that area tend to be waning. \u2026 And then it provides a lot of nectar and a lot of pollen, so it\u2019s an important species ecologically.\u201d<\/p>\n
Once a petition for a flowering plant like Washington Jacob\u2019s Ladder is submitted, it can take several years for a decision to be made. The process is lengthy: An initial review takes 90 days, and then, if a listing \u201cmay be warranted,\u201d an additional yearlong review will occur before a decision is made.<\/p>\n
If the Fish and Wildlife Service does not meet these deadlines, the Center for Biological Diversity will file a lawsuit.<\/p>\n
\u201cThat is something we have to do pretty often in order to get the federal government to actually move forward on these petitions,\u201d McManus said.<\/p>\n
The U.S. Fish and Wildlife Service did not respond to a request for an interview.<\/p>\n
A major reason that plants like Washington Jacob\u2019s Ladder become endangered is climate change and agricultural pressures, McManus said.<\/p>\n
\u201cYou have plants that live in really specialized habitats,\u201d said Dr. Jeremiah Busch, a professor of ecology, evolution, and population genetics at Washington State University. \u201cAnd then, when folks are using those lands, it\u2019s difficult for the species to persist in the long term.\u201d<\/p>\n
\u201cWater is becoming more scarce across the spectrum, and it\u2019s definitely starting to cause problems,\u201d McManus said. \u201cBut I think a lot of those consequences are still ahead of us, because you have plants like Washington Jacob\u2019s Ladder that live for a really long time. So, I think that there\u2019s a good chance we\u2019re going to see accelerating rates of extinction and endangerment for plants in the coming decades.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Washington Jacob\u2019s Ladder has existed on the Columbia Basin for thousands of years.
