California’s tule elk population has received support in past years. But concerns over a series of deaths of a herd at Point Reyes National Seashore has prompted outrage and in-fighting. Here’s more from Western Watersheds:
“There’s nothing ‘natural’ about fencing in wild animals and denying them adequate food and water,” said Deb Moskowitz, president of Resource Renewal Institute in Mill Valley, California, one of three organizations that sued the NPS in 2016 after it was disclosed that 250 of the park’s Tule elk had died. “This isn’t an act of God. It’s NPS official policy.”
“The NPS provides grass and water for cattle, but wildlife must fend for itself. Tragically, we can expect more elk to suffer and die this summer if the Park Service continues to do nothing,” she added.
In October 2020, park visitors and wildlife advocates alerted the NPS at the Seashore that most of the water sources in the elk reserve had dried up, offering photos of several elk carcasses as evidence. The NPS dismissed the concerns and insisted there was sufficient water for the elk in seeps and springs within the elk enclosure. In its press release yesterday, the NPS did not indicate when the 152 elk deaths occurred, but attributed them to a lack of available forage.
“The Tomales Point elk fence blocks these wildlife herds from migrating out of a narrow spit of land to find better forage and fresh water,” noted Laura Cunningham, California Director at Western Watersheds Project. “During the ongoing drought, we have been advising the Seashore that the Tule elk cannot extract enough metabolic water from dry forage to make up for the lack of adequate free water in existing stock ponds and seeps. These rare California native elk deserve better care in a national park unit.”
Here’s the test of the National Park Service’s release:
POINT REYES STATION, Calif. – Today, the National Park Service (NPS) announced that the population of three tule elk herds at Point Reyes National Seashore stabilized or declined in 2020. The park manages a fenced herd at Tomales Point and two free-ranging herds in the Limantour and Drakes Beach areas.
Investigations of dead elk, observations of living elk, and range assessments conducted by park staff in coordination and consultation with wildlife managers and veterinarians from the California Department of Fish and Wildlife (CDFW) suggest poor forage quality is the underlying cause of these population changes.
The herd at Tomales Point declined from 445 to 293 elk, similar to past declines in this area. The other two herds stabilized or declined over the same time period.
The range carrying capacity for tule elk at Tomales Point is estimated at 350 individuals. Over the past 25 years, the Tomales Point elk population has fluctuated between 280 and 550 individuals. The herd’s population tends to increase incrementally during favorable conditions, with the population expanding beyond carrying capacity, followed by less favorable conditions and subsequent population declines.
In 2020, the population of the free-ranging Limantour herd declined from 164 to 155 individuals and the Drakes Beach herd stabilized and increased by one from 138 to 139 individuals. In the prior three years, the Drakes Beach herd otherwise increased by an average of 14% per year. These census results, along with necropsies, observations of living elk, and assessment of range conditions suggest poor forage quality caused by drought conditions exist parkwide.
NPS management of elk at Tomales Point is guided by the 1998 Tule Elk Management Plan (10,680 KB PDF) which predicts a series of modulated swings of population growth and decline in this herd, a process called natural or self-regulation. The decline in the number of elk at Tomales Point this year and in the past, along with subsequent increases, are within normal and predicted population fluctuations.
Although the NPS and CDFW believe the elk population declines are drought-related, there is no evidence that the population decline is due to dehydration and a lack of water. Park staff mapped water sources and monitored water conditions at Tomales Point on a regular basis from July to November, confirming adequate water supplies are available for the elk in the many creeks, seeps, and springs distributed throughout the reserve. Conversely, the nutritional quality of forage is exacerbated by ongoing drought conditions.
The tule elk at Tomales Point are not being considered as part of the ongoing General Management Plan Amendment, which addresses the active ranching areas in the park and the free-ranging tule elk in those regions. The National Park Service is committed to maintaining three healthy herds of tule elk at Point Reyes National Seashore.
