Rodney Sidloski, executive director of HELP International, shows how birds nest in a buffaloberry bush low to the ground, made possible by the large thorns on the bush which prevent the birds from being taken by predators. This bush is on an 80-acre parcel of city land that was treed by HELP volunteers about a decade ago, and this is a sign the habitat is taking in this treed area. Sidloski provided tours on Sunday of the areas HELP has planted trees in, to show they should be allowed to stay a little while longer on the city-owned farm land; their lease on that land expired on Oct. 31.
