Sedgwick Reserve

19 Jan, 04 PM - 28 Jun, 05 PM

We are testing the constraints on the distribution of two exotic Avena species: A. barbata and A. fatua. In particular, we are looking at how responses to specific soil types act in conjunction with competitive interactions to affect the per capita growth rates of each species. The plots will be located close to the serpentine hummocks where I started my 'exotic species-extinction debt' research last year (near Jonathan's Candi site). I am planning to put in 48 plots in total, with each plot measuring 20 x 20cm. Each plot will either be in an area that is dominated by Avena fatua or Avena barbata or both. Half of the plots will be cleared of exotic grasses (the other half untouched), and I will sow in seeds of both species. The seeds will be from the reserve (the same location -- where I cleared some grasses last year). The plots will be marked with small flagging tape and corner pegs. Once the grasses are above knee high, they will be very difficult to find unless you know where they are. This project will only run for this growing season - I will pull out all flagging and corner pegs in June.
