Riparian forests are important for the structure and functioning of stream ecosystems, providing structural components such as large woody debris (LWD). Changes in these forests will cause modifications in the LWD input to streams, affecting their structure. In order to assess the influence of riparian forests changes in LWD supply, 15 catchments (third and fourth order) with riparian forests at different conservation levels were selected for sampling. In each catchment we quantified the abundance, volume and diameter of LWD in stream channels; the number, area and volume of pools formed by LWD and basal area and tree diameter of riparian forest. We found that riparian forests were at a secondary successional stage with predominantly young trees (diameter at breast height \10 cm) in all studied streams. Results showed that basal area and diameter of riparian forest differed between the stream groups (forested and non-forested), but tree density did not differ between groups. Differences were also observed in LWD abundance, volume, frequency of LWD pools with subunits and area and volume of LWD pools. LWD diameter, LWD that form pools diameter and frequency of LWD pools without subunits did not differ between stream groups. Regression analyses showed that LWD abundance and volume, and frequency of LWD pools (with and without subunits) were positively related with the proportion of riparian forest. LWD diameter was not correlated to riparian tree diameter. The frequency of LWD pools was correlated to the abundance and volume of LWD, but characteristics of these pools (area and volume) were not correlated to the diameter of LWD that formed the pools. These results show that alterations in riparian forest cause modifications in the LWD abundance and volume in the stream channel, affecting mainly the structural complexity of these ecosystems (reduction in the number and structural characteristics of LWD pools). Our results also demonstrate that riparian forest conservation actions must consider not only its extension, but also successional stage to guarantee the quantity and quality of LWD necessary to enable the structuring of stream channels.

O objetivo deste estudo foi analisar a estrutura e as espécies arbóreas ocorrentes num remanescente de floresta estacional decidual na Fazenda Carandá, Sub-Bacia da Lagoa Negra, Ladário, MS (19º 06' 18" S e 57º 31' 09" W). A amostragem foi realizada em 1997 utilizando-se o método de parcelas fixas (10 m x10 m), num total de 20 parcelas contínuas, perfazendo uma área de 2.000 m2. As espécies que ocorreram com maior número de indivíduos foram: Senegalia polyphylla, Casearia gossypiosperma, Acosmium cardenasii, Senegalia nitidifolia, Helietta puberula, Cnidoscolus cnicodendron, Aspidospermasp. e Luehea paniculataque totalizaram 52% da amostra, já as espécies com maior valor de importância foram Senegalia polyphylla, Cenostigma pluviosum, Acosmium cardenasii, Cnidoscolus cnicodendron, Senegalia nitidifolia, Hymenaea courbaril, Casearia gossypiosperma, Astronium fraxinifolium e Anadenanthera colubrina perfazendo 50,3% do VI total. O remanescente apresenta uma riqueza de espécie e um índice de diversidade de Shannon (H') com valores superiores ao padrão observado em outros remanescentes de florestas estacionais deciduais da região. |
