The good news is that there were lots of days during August with precipitation somewhere on the refuge - 18 days. The bad news was that this precipitation was often limited in amount as well as in area upon which it fell. The refuge-wide average was 38.1 mm (long-term average is 42.3 mm). The northern portion of McKenzie Flats got the largest amount of rain with the partial met station near Black Butte getting 69 mm. The South Gate station on the east side came in with only 23.6 mm.
The REU Symposium is this Friday, August 8th!
The students have been working hard these past 11 weeks and would love it for you all to come and listen to what they have been up to. The symposium starts at 8:45am and runs to about 3:00pm. We are providing refreshments and lunch. Talks will be held in the SERF Conference Room.
This year there are 14 Biology REU students presenting their independent research projects and 2 Art in Ecology REUs presenting the art they have produced over the summer.
It should be a great event!
Driving Directions to the Station:
Sevilleta's monsoon arrived late. Actually monsoon level moisture arrived early but refused to fall from the sky in sufficient quantities until late in the month. There were numerous small to medium shots of rain for the first half of the month. This was followed by a hot and dry spell. Wetter and more wide-spread storms returned for the last 3 days of the month. These not only "officially" started the monsoon but also pushed the average rainfall for the month past normal.
Monsoon Prediction Contest Winner
Remember the Monsoon Contest? Yes, it had still been going on.
Despite big floods in other parts of the state, the Sevilleta Refuge
continually missed out on a "big one".
Yesterday afternoon (July 29) a storm swept through portions of the
Sevilleta and beginning at 7:38 MDT the Cerro Montoso met station
received a total of 25.8 mm of precipitation. Other stations on the
east side of the refuge got sizable amounts as well while the west
side got smaller amounts and the South Gate station on the east side
Thursday night, July 31, 2014 the UNM Sevilleta Field Station Summer Seminar speaker is Seth Newsome presenting " Examples of how to use chemistry to study animal ecology: surf (sea otters) and turf (kangaroo rats)." Dr. Newsome is an Assistant Professor of Biology at the University of NM. His research focuses on the utilization of stable isotope biochemistry as a tool for measuring the fluxes of energy and materials among components of both past and present ecological systems.
Summer seminar talks are at the UNM Sevilleta Field Station Conference Room.

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.
