| Description
| - The post-fire seedling establishment in relation to microsite conditions and relationships of seedlings (saplings) to older tree individuals was studied for two treatments (i.e. burned and unburned sites) in an area known as the pitch pine (Pinus rigida) ridge on Hill Island, St. Lawrence Islands National Park, Eastern Ontario. P. rigida is a rare tree species in Canada at the northern limit of its range. P. strobus (eastern white pine) and Quercus alba (white oak) are also common species of the site. The negative correlation between density of mature pitch pine trees and total canopy cover and hardwood density was confirmed in unburned plots on the ridge. On the other hand, P. strobus density was positively correlated with those parameters. The density of P. rigida seedlings is higher (by 48%) and P. strobus seedlings lower (by 82%) in burned plots than in unburned plots. Seedling recruitment was also dependent on the occurrence of seed trees of both species.

- Ecese semáčů Pinus rigida a P. strobus byla studována v chráněném území Hill Island v národním parku St. Lawrence Islands (východní Ontario, Kanada) ve dvou experimentálních variantách, tj. na ploše po aplikaci zemního požáru a ploše požárem nezasažené. Na nespálené části studovaného území byla nalezena negativní korelace mezi hustotou dospělých plodných stromů P. rigida a celkovou pokryvností stromového patra a hustotou listnatých druhů dřevin. Naopak stromy P. strobus byly s uvedenými parametry pozitivně korelovány. Hustota semenáčů P. rigida byla vyšši a P. strobus nižší na spálených plochách ve srovnání s nespálenými. Hustota semenáčů P. strobus byla ve studovaném území obecně vyšší než u P. rigida, a to zejména vlivem dlouhodobé absence požárů, které stimulují generativní i vegetativní reprodukci P. rigida. Absence požárů umožňuje rozvoj populace P. strobus, která je jinak požáry výrazně omezena. (cs)
