• Title: Invasion Dynamics at Harvard Farm 2018
• Group Project Leader: Martha Hoopes
• Mentors: Martha Hoopes
• Collaborators: Martha Hoopes
• Project Description:

  Questions: How does grazing intensity alter invasion dynamics in New England grassland systems with a focus on plant community structure and function, biodiversity, and the spread of invasive species?
  
  This project addresses how grazing intensity drives the relationship between invasions dynamics and native diversity in the New England landscape. Agricultural land is a vital but vanishing part of the New England landscape. The Harvard Farm, a pasture adjacent to the Forest, presents a unique opportunity to work at the interface between conservation biology, invasion ecology, sustainable agriculture, and basic research in ecology. The grasslands at Harvard Farm have been managed since 2013 with a range of grazing practices by local dairy farmers, with intensive grazing, rotational grazing, and hay-making as the three intensities.
  
  This project relies on intensive plant community census work at Harvard Farm and may involve experimental work to explore differences in propagule pressure and the different effects of altered propagule pressure and establishment under different grazing regimes. Central data will be plant community composition in the context of grazing and invasive species distribution and spread. The expectation is that students will work together to collect census data from 27 established plots and that each student will also work with mentors to devise and complete a project exploring the spread and community impacts of a non-native species (e.g., Rumex spp. Cirsium spp., and Trifolium spp.).
  
  The student researchers will spend the majority of their time in the field, with an emphasis on analysis work by the last two weeks. They should be comfortable working independently in a pasture setting with dairy cows occasionally present, and be willing to learn plant identification skills. Martha Hoopes, based in the Northampton area, will be at HF weekly throughout the field season.
  
  Student Expectations:
  The student researchers will be involved in the design of the study and statistical analysis, so familiarity with quantitative analysis software like R and ArcGIS will be desirable, as will skills in plant identification and field research methods.
