The Environmental Monitoring and Management Alliance (EMMA) is examining the effects of deer overabundance on forest regeneration at seven upland oak forest sites centered in the Hudson Valley. These data, coupled with deer management programs, will allow us to both assess the impact deer are having on the survival of native species and evaluate the effectiveness of various deer management strategies across the region.

• Plot Establishment
  • dataset_eml_methodsStartDate: 2013-01-01
    
  • dataset_eml_methoddescription: Three pairs of 10 m x 10 m permanent plots were established in two unique locations. The two locations are characterized by relatively level terrain with a mixed oak overstory. The paired plots are separated from one another by a 5m buffer. The unfenced and fenced treatments were randomly assigned to the plots at each location. Fenced treatment plots were enclosed by a 2.5m-tall fence. A small (~25cm x 25cm) hole was cut at ground level on each side of the fence to allow smaller animals access to the fenced area. To permanently identify the unfenced plots, all four corners were marked with metal fence posts. A corner of origin was identified (to facilitate locating trees, saplings, etc. in the following years using a grid system). Sampling occurs in the summer, ideally in July, on the year of installation and every 5 years afterwards.

• Sapling Layer
  • dataset_eml_methodsStartDate: 2013-01-01
    
  • dataset_eml_methoddescription: All individuals whose growth habits are designated as “tree” by the New York Flora Atlas, who are between 0.5 and 2 m tall with at least 50% of their stem(s) emerging from the ground inside of the plot will be evaluated in the sapling layer the year of exclosure installation and every 5 years afterwards. Each stem that emerges from the ground at a distinct location is considered a sapling. Saplings are tagged and assigned a number. The coordinate position (X and Y distance from the designated “origin”, in meters) is measured, primarily so that researchers can find saplings whose tags have fallen off between monitoring rounds. The presence/absence of browse, species, and undisturbed height (cm) to the tallest bud (without stretching the shoot) are measured.
  dataset_eml_methodsQAQC: Data is proofread two times after entering.
