LIDICKON 1981 Sun, 9 aug. That it was not coming. So I walked back to Marshalkowska St. & took the 2 bus sequence to get to the Instytut. I finally arrived about 0930. After some discussion & glass of herbata, 5 of us went to walk in nearby Kampinos Forest. The group included Krystyna, Bogumila Oleck, Wacek Malinowska & his consort Barbara. Oleck, an ornithologist was originally going to take me to a ham listel place in the forest for a small birding trip, but a car was not available. We helped Wacek & Barban run 3 ~ 7 grids (25 x 25m with 25 line traps each) in the forest. Wacek is interested in studying spatial temporal information transfer, & the interacti of these 2 dimensions in the small natural communities. Saw olive: Clostionomyg glerrolus, Microtus agrestis, Microtus oeconomus (within area), Apodemus flavicolis, A. sylvestris, A. agrarius, and Micromys minutus. Only with Krystyna's help did they seem to be able to identify the micratus & the A. sylvestris. I took a few photos including habitat - shots for both species of Micromys. Also saw beaver food made by ??? one of 3 pairs introduced several years ago into the forest. Then he visited a fig or fox farm where Krystyna is studying Rattus & Mus populations in the barns & making trap-line transsects from the barns across adjacent meadows out into the Forest. The next problem is
