BEMP Intern Gary Johnston to Work With 10+ Years of Jackrabbit Data from Sevilleta LTER

This spring, UNM Bosque Ecosystem Monitoring Program (BEMP) intern Gary Johnston will work with the Sevilleta Long-Term Ecological Research (LTER) network and the Valles Caldera National Preserve to process over 10 years of jackrabbit survey data as part of an independent study (Biol 499).

November 2014 - Met Central - Yo-Yo Temperatures

November temperatures came in just about average for the month although few of the daily temperatures actually ran at normal. November started warm but a cooling storm brought some early moisture to NM. Unseasonable warmth returned until the 12th when a Polar Express brought extremely cold temperature down through the eastern side of the state with only some of it leaking through into the central part of the state.

October, 2014 Met Central - Winter is slow coming

October began the new 2015 water-year. On average, October is the 4th wettest month of the year, following July, August, September. However it seems that the Sevilleta rarely sees the average precipitation during October but rather often either extremes near 0 or on par with the wetter months of the summer. Sevilleta saw some moisture from another hurricane. Early in the month Hurricane Simon provided the first real moisture of October.

September 2014 Met Central - Thanks Hurricane Odile.

Hurricanes to the rescue. Moisture associated with Hurricane Odile contributed much of the September moisture at the Sevilleta. The refuge, average total for the month was 57.8 mm; of this 42.4 mm fell during the 3 day period of Sep 15-17. This makes September the wettest month of 2014 so far. It is also the 5th wettest September in Sev LTER's 26-year record.

Hurricanes can be our friends

Hurricanes can be our friends. Actually the remnants of hurricanes can be our friends. This is the time of the year that Pacific hurricanes sometime come to the southwest to die. Moisture carried by or directed by these tropical storms can have a big impact on our fall moisture. Of course sometimes they miss us and drop all of their moisture in other areas. This was particularly the case with Hurricane Norbert. It dropped inches of rain in Arizona but did little for NM. Hurricane Odile looked more promising. Big flooding rain amounts were predicted for much of New Mexico.

Sevilleta LTER Overview

The Sevilleta LTER (SEV) studies fundamental ecological concepts and theories through a comprehensive and interdisciplinary research program guided by the general question:how do abiotic drivers and constraints affect the pulse dynamics and stability of aridland populations, communities and ecosystems?   We focus intensively on Chihuahuan desert grassland and shrubland, juniper savanna and pinon-juniper (PJ) woodland around the Sevilleta National Wildlife Refuge in the Rio Grande Valley in central New Mexico.
