The basic goal of construction of the database was gathering and analysing of archival and contemporary floristic data referring to the area of Central Poland. Registered information considers the stands and characteristic biological and ecological traits of particular taxa. Life forms, indices of ecological requirements, the phytogeographical elements, protection and threat status are among them. The database enables the presentation of geographical distribution of taxa in the area of Central Poland with the cartogram method based on the grid of 2 km2 according to the Distribution Atlas of Vascular Plants in Poland (Atpol).

The most important type of forest community in RNP is Dentario glandulosae-Fagetum. Potential and real vegetation, as well as forest stand maps were used to analyze changes of the age and species structure of beechwood stand from 1946 to 2001. Beechwoods were dominated by two species: fir and beech. During the last 50 years their proportion has entirely changed and the share of oldest groups of stand (over 120 years old) has increased significantly.

The first census was carried out in the period of 1968-1970, and the second census in the period of 1998-1999. In 1998-1999 the occurrence of four species of amphibians, 41 of birds and 15 of mammals was recorded. In comparison with investigations from 1968-1970 two species of amphibians, two species of mammals, and nine species of birds were found to have disappeared from the reserve. In the census carried out in 1998 and 1999 we recorded 22 new species of vertebrates: one new species of amphibian, five species of mammals, and 16 species of birds. The recent observations showed a decline in the abundance of amphibian species in the reserve, especially in the closest vicinity to the urban development around the city of Tomaszów Mazowiecki. The quantitative data on birds showed an increase in the numbers and abundance, which was mainly pronounced in the group of forest species, especially cavity and shrub nesters. We suggest that these changes are directly related to the succession of forest vegetation and its developing vertical structure, as well as to an increase in the forestation of the reserve area.

To improve precision of age determination on the basis of plumage characteristics a scheme of post-juvenile moult was investigated in approximately 1200 first-year Common Snipes caught during autumn migration in central Poland. Post-juvenile moult was commenced from body feathers followed by moult of rectrices, lesser/median wing coverts and tertials. Moult sequence showed high inter-individual variability and was started in rectrices (36.9%), wing coverts (25.3%), tertials (8.4%) or simultaneously in several of these tracts of feathers (29.4%). Moult of rectrices was finished before completion of moult of wing coverts and tertials. Moult of tertials finished as the last from all age-indicative tracts of feathers. Consequently, tertials were suggested as the most useful for ageing of first-year Common Snipes in an advanced stage of moult. There was no case of moult of the outermost tertial in first-year birds. The second tertial from distal side of wing was moulted as the last one within this tract of feathers and thereby should be of special interest during plumage examination.
