Silver lime (Tilia tomentosa Moench) in forest vegetation of Zrinska Gora

The research of forest vegetation was performed in the area of Zrinska Gora Mt (Central Croatia) by the principles of the standard Braun-Blanquet approach. Zrinska Gora Mt is situated on the south edge of the Pannonian plain, phytogeoraphically it has weak Dinaric influence, and furthermore it is south-west edge of distribution of Tilia tomentosa in natural forest communities. From a total of ten forest associations recognized in Zrinska Gora Mt silver lime is present with varying abundance in 7 of them. The highest abundance Tilia tomentosa has in specific ditches and ravines, where as dominant species forms the community of noble hardwoods. Silver lime stands are distributed in altitudinal belt from 270-360 meters and they are developed fragmentary in specific habitats. They are generally characterized by large ravines with inclination of 20-40˚, often a high percentage of rockiness, springs and constant moisture. Rockiness percentage ranges from 10 to 35 %, with the bedrock made mostly of carbonate flysch, calcareous clastic sediments and blocks with colluvial material. Colluvial soil is deep, with less prominent layers as a result of unequal deposition of materials. Above the ravines with silver lime usually follow stands of beech or sweet chestnut, and on the higher slopes and southern exposures sessile oak forest, with much smaller proportion of silver lime. In comparison to the surrounding beech forests of all. Fagion sylvaticae and suball. Luzulo-Fagenion, they are characterized floristically by share of the Illyrian elements. Tilia tomentosa stands are affiliated within the alliance Tilio-Acerion and its suballiance Lamio orvalae-Acerenion.
