REC AO Blog
Since the 1960's HREC has maintained a unique research facility - a set of lysimeters. Each lysimeter consists of a steel tank, which is filled with soil, plumbed to collect all water draining out of that soil, and buried into a hill slope so that the soil within the tanks is similar in conditions to blocks of soil found in the natural system. This unique setup allows researchers to test how different treatments impact the loss of water, nutrients, pesticdes, etc., from ecosystems. This photo shows HREC's current 72-tank lysimeter facility, recently built by HREC staff with funds from the "National Research Initiative Cooperative State Research, Education and Extension Service".
The Western Harvest Mouse (Reithrodontomys megalotis) is locally common throughout the western two-thirds of the of the United States (lower 48 states except for the high Rocky Mtns). This secretive rodent prefers open mesa habitats with thick grass and forb vegetation and a build-up of dense litter. At HREC they can be found in the long-ungrazed portions of the Center. Bristly fur, a long bi-colored tail, and whitish feet are all characteristics of this native species.
HREC is blessed with location as the Center is located at a "hub" of climate zones and maritime influence and soil and elevation differences. As a result, HREC has over a dozen species of oaks that can be found on on the Center. Here you see a Coast Live Oak (Quercus agrifolia) with fresh new leaves forming and catkins ready to bloom. Coast Live Oaks are only found at scattered locations at the lower elevations on the west side of the Center.
Killdeer are the most common species of shorebird that utilize HREC, and the only shorebird species that nests here. This nest was placed by the parent killdeer in open gravel next to the HREC greenhouse, and was staked by HREC staff to prevent people from walking or driving over the nest. Two days ago the eggs hatched, and yesterday the "mom" led the precocial chicks, four of them, away from the nest site and down to Parson's Creek gravel bar.
The Hopland Research & Extension Center is accessed by University Road which is a county road. It is one of the last Mendocino County roads with a livestock "cattleguard" ( metal grate-like structure at ground level that prevents livestock from crossing without the need for a gate) maintained by the county. At times when HREC has sheep grazing in Vassar Pasture, visitors get the thrill of seeing sheep on the road ... literally!
