MANAGEMENT OF THE VEGETATION UNDER ELECTRICAL ENERGY TRANSMISSION LINES IN THE SERRA DE BATURIT\uc9
Entre os impactos diretos causados pela instala\ue7\ue3o de redes
el\ue9tricas sobre a vegeta\ue7\ue3o e o solo ressaltam-se a
fragmenta\ue7\ue3o de trechos de mata, os efeitos de borda
decorrentes da derrubada de \ue1reas florestadas, o estabelecimento
de corredores sob as linhas de transmiss\ue3o de energia e a
acelera\ue7\ue3o de processos erosivos do solo. Objetivou-se, no
presente estudo, propor alternativas de manejo racional da cobertura
vegetal de mata atl\ue2ntica em \ue1reas sob linhas de
transmiss\ue3o de energia el\ue9trica (ALTEEs), instaladas na Serra
de Baturit\ue9, Cear\ue1. Foram selecionadas e delimitadas ALTEEs
situadas na vertente barlavento e nos intervalos altitudinais abaixo de
600, entre 600 e 800 e acima de 800 metros, em redes de m\ue9dia
(13,8 kV) e alta tens\ue3o (69 kV). Foram selecionadas e avaliadas
\ue1reas n\ue3o-perturbadas, consideradas como referencial no
estudo comparativo com as ALTEEs. Os resultados apontaram que o manejo
da vegeta\ue7\ue3o em \ue1reas sob linhas de transmiss\ue3o de
energia deve considerar principalmente os seguintes aspectos: (1) o
h\ue1bito de crescimento das esp\ue9cies em \ue1reas
n\ue3o-perturbadas; (2) a taxa de crescimento da vegeta\ue7\ue3o;
(3) a\ue7\uf5es distintas nas regi\uf5es imediatamente abaixo da
rede el\ue9trica, na faixa de servid\ue3o e acima da faixa de
servid\ue3o. A execu\ue7\ue3o do plano de manejo, associado
\ue0s constantes avalia\ue7\uf5es t\ue9cnicas,
possibilitar\ue3o a adequa\ue7\ue3o da metodologia para as
diferentes situa\ue7\uf5es ambientais da Serra de Baturit\ue9
e/ou outras localidades.Forest fragmentation, board effects, establishment of corridors without
vegetation and the acceleration of soil erosive processes are some
direct impacts occurring on the vegetation and soil due to installation
of electrical transmission lines. The goal of the present study was to
propose alternatives for the sustainable management of the Atlantic
Forest in areas under electrical transmission lines (ALTEEs) installed
in the Baturit\ue9 Mountain, Cear\ue1, Brazil. It was selected and
delimited ALTEEs located in the windward slope at the altitudinal
ranges below to 600, between 600 and 800 and above to 800 meters in
electric networks of low (13,8 kV) and high tension (69 kV). It was
also selected undisturbed areas considered as referential in comparison
to the ALTEEs. The results pointed out that management of the
vegetation in areas under electrical transmission lines should mainly
consider the following aspects: (1) growth habit of tree species within
undisturbed areas; (2) growth rates of the vegetation; (3)
differentiated management procedures on the vegetation situated
immediately below the electrical lines, within intervention area and
beyond to the intervention area. The execution of the management plan
associated to the constant technical evaluations will make possible the
adaptation of the methodology for the different environmental
situations in the Baturit\ue9 Mountain and/or other regions
