Vegetation Management. Carrizo Plain National Monument


Grazing Decisions and Rationale 2012

One of our key vegetative goals is to restore and maintain a mosaic of natural communities to benefit the Monument’s biodiversity. Some of our endangered animal species may struggle if the non-native vegetation becomes too thick and dense. The Carrizo Plain National Monument Resource Management Plan (RMP) prescribes that excessive vegetative growth be reduced in Core Areas to help maintain native animal species. The results of vegetation monitoring this year in the Core Areas for these species have not shown a need to reduce vegetation and we have not had to apply grazing for that purpose. The species objectives driving these decisions are contained in the Conservation Target Table Attachment 5 in the RMP. These decisions were based on the habitat criteria requirements for the blunt nosed leopard lizard objective (page ATT-5-55) and the fairy shrimp objective (page ATT-5-59).

While all Core Areas for the fairy shrimp, blunt-nosed leopard lizard and giant kangaroo rat were considered and monitored, no areas met the criteria this season and were dropped from further consideration.

Summary of Vegetation Management Actions taken October 2011 through September 2012 to meet the Carrizo Plain National Monument RMP Biological Objectives:

Livestock Grazing:

Mountain Plover (MOPL) Core pastures: Assessments in August – September 2011 revealed adequate amount of suitable MOPL habitat present; no treatments needed in October for this purpose.

Blunt-nosed leopard lizard (BNLL) Core pastures: Late January assessments had 600 lbs/ac. and limited growth.  Mid-March assessments were 200 lbs/ac.; no treatments needed for this purpose.

Giant kangaroo rat (GKR) Core pastures: March assessments were 200 lbs/ac.; no treatments needed for this purpose.

Fairy Shrimp pastures: March assessment determined no treatment needed for this purpose.removed.

Fire Management:

An area was prepared for a prescribed burn but early season wildfires prevented fire crews from being available for our burn.

Other Restoration:

Monitoring of previous restoration sites has shown success.
