The Monthly Bighorn Report
January 2010

 

Here we provide brief reports about ongoing studies and current events related to bighorn sheep conservation. Please check back frequently!

2009 Bighorn Institute Golf Classic
On November 22nd and 23rd we held our annual Golf Classic fund-raiser. Once again, the tournament was held at Stone Eagle Golf Club with the pre-tournament party at The Reserve. The fund-raiser was a success and raised much-needed funds for the Institute’s research and conservation efforts for the endangered Peninsular bighorn sheep. We are sincerely grateful to all who helped make the Golf Classic a success.

 
Recent Rain
The Coachella Valley received a mere two inches of rain in 2009, half of which didn’t come until late December. However, 2010 is off to a very wet start. The Valley received an entire year’s worth of rain (over 4 inches) during 6 consecutive days in mid-January! The recent rain has provided the mountains with lush green plant growth and replenished water sources. The bighorn sheep are taking advantage of this new forage, which has arrived just in time for lambing season.



A beautiful double rainbow appeared after
the rain.

 

Wild Peninsular Bighorn Population Update
We are pleased to report that there were no collared bighorn mortalities in the northern Santa Rosa Mountains (NSRM) in 2009. However, there were a number of rams and a ewe that we have not seen for a few years that we censored out of the population at the end of December. It’s not to say that these sheep are dead, they may be elsewhere in the range, but they no longer inhabit the herds we track. One female lamb survived to yearling age so there are now approximately 63 adult bighorn in the NSRM (35 females and 28 males).

In the San Jacinto Mountains (SJM) we documented 5 collared bighorn mortalities in 2009. Four lambs (2F, 2M) survived to yearling age and are now counted as adults. There are now approximately 28 adult bighorn in the SJM (16 females, and 12 males).

Captive Herd
There are currently 7 ewes and 3 rams in the Institute’s captive herd. The female lamb is now a great looking yearling. The ewes are showing signs of pregnancy and we are optimistic that we will have a good lambing season this spring. There are 6 ewes that should give birth.

 

 Lambing Season
It’s that exciting time of the year again when Peninsular bighorn sheep give birth. Peninsular bighorn lambing season is typically January through June with most Peninsular bighorn lambs born between February and April. Lambs have come early again this year in the northern Santa Rosa Mountains as we have already documented two adorable newborn lambs. Both lambs were born around January 15th and we anticipate there could be more lambs on the ground now. We look forward to another exciting lambing season and hope for better lamb survival.

 

Membership Meeting
The Institute’s annual membership meeting will be held at the Institute on Saturday February 20th at 8:30am. We will discuss our accomplishments in 2009, plans for 2010 and elect the Board of Directors. The meeting is open to all members. If you would like to attend please give us a call at 760-346-7334. Hope to see you there!
