RESUMO
O bioma florestal mais característico do Sul do Brasil é a Floresta Ombrófila Mista, fortemente marcada
pela presença da espécie Araucaria angustifolia. Entretanto, a exploração irracional e descontrolada desta
espécie reduziu drasticamente sua área de ocorrência a 2% de sua área original. Assim, esforços devem ser
feitos para auxiliar e promover sua regeneração natural, visando a sua preservação e o uso sustentável de
seus recursos econômicos. Com o objetivo de avaliar a germinação, sobrevivência e predação de mudas
e sementes de Araucaria angustifolia foi implantado um experimento em delineamento inteiramente
casualizado, no qual foram investigados os efeitos de dois fatores com dois níveis cada (tipo de plantio: puro/
misto; material plantado: mudas/sementes), com três repetições, perfazendo um total de quatro tratamentos.
Após 14 meses restaram 17% das covas ocupadas por mudas e 14% das ocupadas por pinhões; 60% das
sementes germinadas foram consumidas pela fauna; o percentual de sobrevivência médio das mudas foi de
41,1% no plantio puro e de 20,0% no plantio misto. No tratamento misto, as perdas de sementes, devido à
ação fauna, foram menores (42,2%) quando comparadas ao tratamento puro (68,9%); o contrário foi válido
no caso das mudas.

ABSTRACT
The most characteristic forest type of southern Brazil is the Araucaria Forest, strongly marked by the
presence of the species Araucaria angustifolia. However, the overexploitation of the species reduced its
range to 2% of its original area. Efforts must be made to support and promote its natural regeneration, seeking
the preservation and sustainable use of its economic resources. Therefore, an experiment was conducted
to evaluate germination, survival and predation rates of seeds and seedlings of Araucaria angustifolia,
analyzed as a randomized factorial design with two factors with two levels each (type of plantation: pure/
mixed; raw material: seeds/seedlings), totaling four treatments, with three replicates each. Fourteen months
after planting only 17% of the seed holes contained live plants; 14% of planted seedlings survived; 60% of
the seeds were consumed by animals. Seedling survival was 41.1% in the “pure” treatment and 20% in the
mixed treatment. In the mixed treatment, seed losses due to fauna attack were lower (42.2%) compared to
the ‘pure’ treatment (68.9%); the opposite behavior was observed in the case of seedlings.
