7. Code 1958 5 August cont- way where the ridges and grasses are more lush and continuous it probably would have yielded a catch similar to T2 & T3. Lemmus appears to occupy the same ground exactly but in limited numbers, M. minutus has not been taken at this station. Suitable alderical low type habitat does not occur in this valley until one goes about 3-4 miles upstream. There is flood plain habitat that looks suitable - ground such as that along T1 - but there is no sign of microtine activity in the flood plain until one reaches a point about 2 miles above Jugo Lake, where I saw some digging and fresh trails along a bank between the flood plain and the river terrace. This sign was probably made by M. minutus. Ondysavum (legume) is again prevalent on the flood plain areas here as on the Okfilek, so there should be sufficient food for populations of M. minutus, at the Jugo Lake sector of the valley. Willow cover is not so good as at Okfilek. No sign of Ondysavum this year on any ground.
