Climate Change Likely to Reduce Range of Joshua Tree

Image
Global warming driven by greenhouse gas emissions is expected to eliminate the iconic Joshua Tree (Yucca breviolia) from 90% of its current range within 60-90 years.  The tree is likely to be limited to the northern portion of its range, according to a study led by the US Geological Survey that looked at how the tree reacted to a sudden climate warming approximately 12,000 years ago.  

The climate study notes that the sudden warming period in the past reduced the Joshua Tree's range, and the extinction of the giant Shasta ground sloth since that time slowed the tree's ability to reclaim lost territory.  The giant ground sloth used to feed on the seeds of the Joshua Tree and spread them far and wide.  Today, small rodents such as squirrels and packrats still feed on the seeds, but do no carry them as far. 

Climate change poses a double threat to desert ecosystems since some energy companies are seeking to destroy desert habitat in order to build massive solar facilities and mee…

Mark Your Calendar: Mojave Desert Land Trust Restoration Event

The Mojave Desert Land Trust and the National Park Service are hosting an event on Saturday, 13 November to restore desert habitat in the Joshua Tree National Park. The efforts will help improve the ecosystem around the Nolina Peak, and will be a good opportunity to learn more about our desert resources while giving back.

You can learn more about volunteer opportunities on the Land Trust's website, or email Miz Seita at mizseita@gmail.com.

Here is the information for the restoration event:

Date: November 13th (Saturday)  
Time: 8:00am - 3:00pm

Location: Meet approximately 1.5 miles from the corner of La Contenta Road and Covington Flat Road along Covington Flat Road. (Please RSVP and I will email a map and directions). Please bring water, lunch, gloves, sunglasses (eye protection), long sleeve shirt, long pants, sunscreen, wide brim hat, and hiking boots.

PLEASE RSVP - contact Miz Seita at 760-366-0542 or email mizseita@gmail.com

Reviewing the draft environmental impact report (EIR) for the proposed 1,555 acre "Hacienda at Fairview Valley" residential project (for more info, see my previous post), a Joshua Tree survey identified at least 3,891 Joshua Trees on the proposed site.  County regulations would require the developer to attempt to avoid impacts to Joshua trees and preserve in-place to the farthest extent possible in order to achieve a “design of excellence.”  If the project progresses toward construction, the developer would have to submit a Joshua Tree plan that identifies specific trees to be transplanted or stockpiled for later transplantation or future adoption.  

The survey approximated that 38% of the trees on the site would be "transferable,"  implying that the rest would likely be cut down and discarded.  You can download the full report on the website of San Bernardino County's Land Use Services Department in the list of EIRs.  Scroll down to the Hacienda project for t…
