Germination and survival of tree species in disturbed forests of the highlands of Chiapas, Mexico
Germination and seedling survival of native tree species were studied in a nursery during June-November 1998 and in forest stands with varying dominance by pines in the central highlands of Chiapas, Mexico during June 1998 - November 1999. Species used are regarded as typical of mid- and late-successional habitats: Cornus disciflora, Cornus excelsa, Drimys granadensis var. mexicana, Liquidambar styraciflua, Persea americana, Quercus laurina, and Ternstroemia lineata ssp. chalicophyla. Nursery treatments included presence and composition of litter collected from replicated plots of three forest types: old-growth forest, mixed pine-oak forest and pine-dominated forest. Germination and seedling emergence of P. americana in the nursery were complete for all factor combinations. C. disciflora and L. styraciflua showed highest germination (p<0.05) when sown in soil from old-growth forest and covered with litter of oak-broad-leaved species. In the field, differences (p<0.05) among forest types (degree of pine dominance) were observed for C. disciflora (lowest germination in pinelands, 17%), D. granadensis (highest survival in old-growth forest, 23%), and Q. laurina (highest survival in pinelands, 54%). Natural recruitment and survival of seedlings were higher in old-growth forests. We conclude that oak litter may favour germination and early establishment of the studied species. However, the reintroduction of some of the studied species (C. excelsa, Q. laurina, and T. lineata) may be attempted with direct sowing on the forest floor of severely disturbed and species-poor pinelands.

Les espèces étudiées sont considérées comme typiques des habitats du milieu et de la fin de la succession; ce sont les Cornus disciflora, C. excelsa, Drimys granadensis, Liquidambar styraciflua, Persea americana, Quercus laurina et Ternstroemia lineata. Les traitements en pépinière incluent la présence et la composition de litières récoltées de parcelles répliquées, provenant de trois types de forêt : forêt surannée, forêt mixte de pins et de chênes et forêt dominée par les pins. En pépinière, la germination et l'émergence des plantules du P. americana sont complètes pour les combinaisons de tous les facteurs. Le C. disciflora et le L. styraciflua montrent les plus fortes germinations (p < 0,05) lorsqu'ils sont ensemencés dans du sol de forêt surannée et recouvert avec de la litière d'espèces de chênes et autres décidues. Sur le terrain, on observe des différences (p < 0,05) entre les types de forêt (degré de dominance par les pins) pour le C. disciflora (plus faible germination en pinèdes, 17 %), pour le D. granadensis (survie la plus élevée en forêt surannée, 23 %), et pour le Q. laurina (survie la plus élevée en pinèdes, 54 %). Le recrutement naturel et la survie des plantules sont plus élevés dans les forêts surannées. Les auteurs concluent que la litière de chêne peut favoriser la germination et le début de l'établissement des espèces étudiées. Cependant, la réintroduction de certaines des espèces étudiées (C. excelsa, Q. laurina et T. lineata) pourrait être tentée par semis direct sur le parterre forestier de pinèdes sévèrement perturbées et pauvres en especes.Germination and seedling survival of native tree species were studied in a nursery during June-November 1998 and in forest stands with varying dominance by pines in the central highlands of Chiapas, Mexico during June 1998 - November 1999.
