The Kennebec Estuary Land Trust invites the public to three workshops teaching participants to care for the land, to gain valuable skills, and to have splendid experiences, in April, May and June:

— GPS tutorial, 9 a.m. to 2 p.m., Saturday, April 13.

Join Kennebec Estuary Land Trust staff member Chris Cabot to learn and practice using Global Positioning Systems. Participants will have an indoor orientation then venture through Thorne Head Preserve in Bath for in-field application of GPS devices and skills.

A limited number of GPS units are available for loan during the workshop. This is a rain-or-shine event with no workshop fee.

Registration is required by April 8.

— Chainsaw Training for Women is 8:30 a.m. to 3:30 p.m., Saturday, May 11.

Women are encouraged to attend a chainsaw use and maintenance course led by veteran wood cutter and part time logger John Cullen.

This is an introductory class on chainsaw safety and homeowner maintenance.

The rain date for this event is May 19.

Cost is $55 per person and includes lunch in the field. Registration required by May 7.

— Botany & Habitat Management is 8:30 a.m.-12:30 p.m., Saturday, June 8.

State ecologist and expert Andrew Cutko is leading motivated property owners to identify the good, bad and interesting plants and habitats on the land.
