Range Restoration

Humans have exerted a major influence on plant communities across MPG Ranch that began with fires set by the Native American and continued with intensive livestock grazing, farming, and herbicide applications.  The overall result of these activities is that low diversity and low productivity plant communities composed mainly of non-native plants cover many areas.  In many cases the existing undesired vegetation is hardy and resistant to replacement, after all it is the stuff that has survived grazing, herbicide applications, and the ranch’s harsh climate.   The updates and reports in this section show the approaches we take to figure out the best ways to restore diverse and productive plant communities.  

 

Rangeland diversification- In some cases we use herbicide applications combined with fire and drill seeding to establish new communities. To see a discussion of those efforts (Click here).

 

Assisted Succession- We have also developed a new approach to restoration of weedy areas using a naturally herbicide resistant initial plant to reclaim weed infestations.  The plant is called sainfoin.  It is a legume that enriches the soil and allows us to kill-off the weeds seed bank before we re-plant.  To see more on this project (Click here).

RESEARCH UPDATE
GREENHOUSE EVALUATION OF ACTIVATED CARBON AMOUNTS REQUIRED TO PROTECT NATIVE SEEDLINGS FROM PRE-EMERGENT HERBICIDES -

Activated carbon shows potential for targeted protection of native seedlings from pre-emergent herbicides. Protected native seedlings may be able to establish the first year without competition.

RESEARCH UPDATE
AERIAL WEED CONTROL EFFICACY -

We treated 600 acres of heavily invaded former rangelands with the preemergent herbicide imazapic in the fall of 2011. Alien plant species cover was determined on 78 sites before and after treatment to evaluate first year treatment efficacy.
