Invasive Fire Ants in Restored and Unrestored Central Valley grasslands

I mentioned earlier that I have started monitoring invasive Argentinian fire ant infestation of Sherman live traps during my rodent trapping periods. Initial data collection began in July 2014 for a subset of trapping days at two of the four locations where I am monitoring wildlife. The number of live traps infested with fire ants was used as an…

Abstract: Burning reveals cryptic diversity and promotes coexistence of native species in a restored California prairie

This poster was presented at the Ecological Society of America annual conference in Sacramento, CA, by my colleague Derek Young, on Aug. 15, 2014 (see http://eco.confex.com/eco/2014/webprogram/Paper50354.html). Authors at that time were as follows: Derek J.N. Young, Dept. of Plant Sciences, University of California, Davis, Davis, CA Lauren M. Porensky , Rangeland Resources Research Unit, USDA ARS, Fort Collins,…

July 2014 Wildlife Sampling: Season Two

Before you start reading this post, you might want to start at the post entitled “Wildlife Use of Native Perennial and Exotic Annual Grasslands: A Comparative Study” (https://kristinamwolf.com/2014/01/31/wildlife-use-of-native-perennial-and-exotic-annual-grasslands-a-comparative-study/). That will explain from the beginning the study design and what we have been doing with this ever-growing multi-trophic, multi-season, multi-scale research investigating wildlife habitat use of restored native…

Can summer watering alter seasonal priority effects and reduce the annual grass weed challenge in a restored grassland?

This post will describe the background, rationale, methods, and some preliminary results for a series of summer watering experiments that I conducted over two years to determine if summer watering in an already restored grassland can produce a strong enough weed flush (exotic annual grasses) to reduce weed challenges in the subsequent growing season. Please see my other…

April 2014 Wildlife Sampling: Here We Go!

The coverboards have all been placed, the t-posts are in the ground and cameras mounted, the traps are ready to be baited, 10-20 years ago half of the sites being monitored were restored with native perennial grasses…. we built it, but will they come? Short answer: In droves. April of 2014 was our first season of sampling…

Wildlife Use of Native Perennial and Exotic Annual Grasslands: A Comparative Study

Hi there! Here I will discuss the general experimental design and questions I am asking with my study comparing wildlife use of paired restored native perennial grasslands (hereafter, “restored”) and unrestored exotic annual grasslands (hereafter “control”). Introduction and Significance Intact native grasslands are some of the rarest ecosystems in the world, and wildlife species associated with…
