O objetivo desta investigação é saber quais os agentes bióticos/abióticos que podem
contribuir para o produtor agroflorestal alterar a composição específica da sua floresta.
Assim, recorreu-se a um inquérito, que cumpriu as questões éticas e obteve parecer
positivo da CEIP. O questionário incluiu informações: sobre a caracterização do
proprietário (idade, sexo, escolaridade, formação profissional). Contém informação
sobre a caraterização da propriedade (regime, área total e florestal, principais espécies,
localização - distrito e concelho). Engloba informação sobre a gestão de riscos florestais
(ocorrência de incêndios, pragas/doenças, espécies invasoras ou outros). Abrange
informação sobre: prevenção de riscos florestais – incêndios: gestão de combustíveis
junto aos caminhos e métodos utilizados, controlo da vegetação espontânea na floresta
e métodos usados, seguro de incêndios florestais, gestão/prevenção de pragas/doenças
e métodos utilizados, gestão/prevenção de espécies invasoras e métodos usados,
gestão/prevenção de outros riscos florestais. E inclui informação sobre a resposta aos
riscos florestais (alterações das espécies e motivos, projeto de mudança). Devido ao
COVID-19, realizou-se o Inquérito através do Google Forms, visando o Alentejo, tendose obtido 33 respostas. Após a receção e tratamento dos dados do inquérito verificouse que 54,5% dos proprietários eram do sexo masculino, 45,5% feminino; a média de
idades é de 50 - 59 anos. A propriedade agroflorestal média foi de >50ha. Os inquiridos
têm como espécies florestais: pinheiro bravo 57,1%, montado de sobreiro 53,6%,
eucalipto e pinheiro manso 35,7%, montado misto 28,6%, outras espécies 25% e
montado de azinheira 17,9%. Conclui-se que os proprietários têm conhecimento dos
riscos florestais, mas não têm influenciado nas suas decisões de gestão florestal;
apenas 11,1% tencionam mudar de espécie. Desses 11,1%, a maior parte pensa
alterar as espécies florestais por razões económicas, escolhendo espécies mais
rentáveis 66,7%. E 33,3% pondera a alteração de espécies florestais por ter sofrido
riscos, nomeadamente, “elevada mortalidade de sobreiros”.
The purpose of this investigation is to know which biotic and abiotic agents may led the Agroforestry Producer to change the specific composition of their forest. A survey was used, which obtained ethical clearance from the CEIP. The survey included information on: the characterization of the owner (age, sex, education level and professional training). Contains information about the agroforestal property (tax regime, total area and forest area, main forest species, location by district and municipality). It includes information on forest risk management (the occurrence of fires, plagues and diseases, invasive species or others). Covers information on: forest risk prevention - fires: fuel management along the paths and methods used, spontaneous vegetation control within the forest and used methods, forest fire insurance, plague and disease management / prevention and used methods, management / prevention of invasive species and used methods, management / prevention of other forest risks and used methods. And it includes information about the forest risk response (changes in forest species and reasons, project for the change). Due to COVID-19, the survey was conducted through Google Forms, reaching the entirety of the Alentejo region, 33 inquiries were registed. After receiving and processing the survey data, it was found that 54,5% of the owners were male and 45,5% female; the average age was between 50 and 59 years. The average agroforestry property was >50ha. Respondents have as dominant forest species: Pinus pinaster 57,1%, cork oak forest – 53,6%, Eucalyptus and Pinus pinea – 35,7%, mixed Quercus suber and Quercus rotundifolia forest – 28,6%, other species 25% and Quercus rotundifolia forest – 17,9%. It is concluded that the owners are aware of forest risks, but these have not influenced their forest management decisions, because only 11,1% will change their forest species. Of that 11,1%, most plan to change forest species for economic reasons, choosing more profitable species (66.7%). And 33.3% consider the exchange of crops for having suffered forest risks, namely, "high mortality of cork oaks forest".
