Lynx Lynx lynx maternal behaviour and dispersal pattern were studied by radio -telemetry in the Białowieża Primeval Forest, E Poland from 1992-1995. From June­-July, 2 females with kittens used 1-4 dens per month, for 5 to 33 days each, Consecutively used dens were 1-3 km apart and were located in inaccessible places. Female movements were concentrated around the den at this time, Mothers left their kittens and returned to them, on average, 3 times per day. Mean time of female's absence from the den was 4 h 20 min. Mean den attendance averaged 4 hours. In August, kittens began to accompany their mother. At this time, each den was used for 2-3 days only and the distances between consecutive dens were 0.5—2 km. Dens were situated in places where a female killed large prey. In August, a female spent an average of 12 h 50 min with kittens, alternating with 4-h of absence. Subadults dispersed at 9-11 months of age, immediately after separation from their mothers. Four subadult males dispersed for 11, 39, 62 and 129 km from their natal ranges. Two subadult females dispersed for 5 and 9 km. Lynx that moved the farthest distances covered most of their routes during the first two months of dispersal, when they moved 20-32 km/month, compared to 3-11 km/month in the later period. Distant emigrations of two adult lynx (55 km by a male and 120 km by a female) were also recorded. Directions and routes of lynx dispersal and emigration were related to the contemporary distribution and availability of woodlands and forest corridors.
This article presents new technological and technical solutions for forest nursery, which were developed recently in Department of Forestry Mechanization at Agricultural University in Krakow and implemented in forest nursery. Fertilizer dispensers equipped with mechanism to mix, loosen, and initial soil thickening were made, in order to enrich the ground with mycorrhizal fungi, fertilization and presowing preparation of soil. Thick seeds spot seeding section of Agricola Italiana type PK seeder was modified in order to use in spot seeding, so now it can sow thick seeds like beech or fir and tiny seeds in double rows which make it a universal seeder to sowing forest trees seeds. Sections, up to 5, mounted on construction can spot sow seed perches in field conditions. In order to use in corridor, sowing field seeder arm was modified by extending it, so it was possible to mount sideways seeding units and tractor can be driven next to corridor. Electrical tool holder was constructed for spot seeding under cover, to which you can mount equipment for soil preparation (sowing fertilizer, mycorrhizal biopreparate dosage, loosing and rolling ground), spot seeder sowing sections or constructed saddle for performing weeding.
