An Ethiopian & Eritrean dinner banquet will be held at the MK Nature Center on Wednesday evening with Eric Yensen as the guest speaker following dinner.

We also are lucky enough to have a field trip to Primrose Hill (Bogus Basin Road, just above Boise) led by Dr. Don Mansfield on Thursday afternoon.

A request for presentations and posters for the Conference is open until January 19th, 2018, please respond to the call for papers (link below). We will have a “To the Point” session (10 minute presentations) to provide a great opportunity to quickly update colleagues on any topic of interest related to Idaho native plants and time for some 20 minute presentations. We are especially interested in new plants for Idaho and inspiring presentations.

The Idaho Rare Plant Conference (RPC) is generally held every other year, and is organized by INPS along with various agencies (such as Bureau of Land Management, Idaho Department of Fish and Game, US Fish and Wildlife Service, Forest Service, etc.), academics, consultants, and others interested in Idaho’s rare plants.

It is an opportunity to learn about rare plants, share information, and network with others of similar interests.

Updating the INPS Rare Plant List, based on new information, is a substantial portion of the RPC. In addition, there are usually a number of talks/presentations on rare plants, conservation issues, or related topics. Dinners (either banquet or informal gatherings) along with conference breaks and poster session offer opportunities to renew or make new botanical acquaintances. Sometimes a field trip has been part of the RPC.
