Major effort begins to restore tortoise habitat
ana maria deixa namorar a sua filha Thirty miles outside of St. George, where the westernmost mountains of Utah slope off into a sea of tangled Joshua trees and desert scrub, a team of volunteers is undertaking the largest habitat restoration research effort yet tried to help the Mojave Desert Tortoise.

Aparecida de Goiânia mensagem de um ano de namoro para namorado John Kellam, a wildlife biologist with the Bureau of Land Management, said the species’ struggles are largely due to fires that tore through the area in 2005 and 2006, clearing out the native vegetation and ploughing the way for invasive plant species to move in.

The hope now is to bring them back, starting with the habitat restoration project.
Two 100-acre research plots have been selected, one at Beaver Dam and one in the Red Cliffs Desert Reserve north of St. George. Some 5,000 native plants are planned to go in at each site, each hand-dug by staff members and volunteers.
The plants, which will be nursed along for months in hopes they thrive, should provide a needed source of food and shelter for the tortoises.
It’s a sophisticated piece of a planning, now being carried out with the simplest of tools — shovels, five-gallon buckets and roll upon roll of chicken wire.
“It’s taken a lot of cooperation to put this together,” said Andrea Nelson, community engagement manager for the Nature Conservancy in Utah, explaining the long process that has come to include a long list of government agencies, conservation advocacy groups and private volunteers.
The Nature Conservancy, Utah Division of Wildlife Resources, U.S. Bureau of Land Management, U.S. Fish and Wildlife Service, Washington County, National Fish and Wildlife Foundation and the University of Nevada, Las Vegas are partners in the effort.
A group of students from Dixie State University are chipping in, earning extra credit, and the volunteers who were working with the American Conservation Experience.
“The site is remote. It’s a little hard to get to, but they’re still willing to come here,” Nelson said.
Crews are following a plan that was aided along by the Nature Conservancy’s “Landscape Conservation Forecasting” method, specially designed for the varying elevations, soils, weather patterns and historical makeup of each habitat, Nelson said.
Volunteer teams are scheduled to head out to the site on Saturday, with others helping at the Red Cliffs site on Nov. 19.
From there, the plants will continue to see regular care, with different techniques used to encourage the growth of seven target species, said Dawna Ferris-Rowley, NCA manager for the BLM’s St. George field office.
As the different techniques are analyzed across the different locations, it will help guide future efforts, she said.
A 5-percent survival rate is generally considered a success, Kellam said.
Tortoise populations in the reserve https://www.mk-photos.de/1420-dde17444-partnersuche-berlin-kostenlos-prozent.html have been holding steady in recent years, at about 15 per square kilometer within the Red Cliffs reserve, but they’re still well behind the numbers recorded before the fires.
