Special Issue Information

Dear Colleagues,

Forest plant communities are plant species that coexist within specific forested environments. These communities share common ecological conditions, including soil type, climate, and topography, which influence their composition and interactions. Their role in ecosystem functioning is crucial, supporting biodiversity, carbon sequestration, and other essential services.

However, the stability of forest plant communities worldwide is currently under significant threat due to a combination of rapid climate change and over-exploitation. Climate change leads to increased tree mortality and limits forest regeneration, resulting in changes to structure and species composition. Large-scale deforestation and intensive land use further exacerbate the situation by modifying habitats, introducing invasive species, and disrupting forest ecosystems.

Despite these challenges, it is essential to recognize that the current state is just a snapshot of the millennial history of forest plant communities’ vulnerability, adaptation, and resilience to external stressors. In this context, palynology plays a pivotal role. By examining pollen data, we bridge the temporal gap, connecting ancient landscapes to our present-day environment. Palynology provides baseline information for conservation efforts and informs models predicting how vegetation will respond to climate change, human activities, and geomorphic processes.

In this Special Issue, we explore how pollen data can help monitor forest plant communities and shed light on their historical changes. This knowledge empowers us to learn from the past, adapt to the present, and make informed decisions for sustainable future forest ecosystems.

Wildfires have had measurable impacts on pollen dispersal in some areas; both facilitation and potential barriers to pollen movement have been reported. These dispersal dynamics in turn affect population genetics and reestablishment of seed-producing plants, at times significantly impacting the successional trajectory of the area in question. However, research on post-fire pollen distribution and occurrence is lacking for the boreal and sub-boreal forests of western Canada, and many communities that have been heavily impacted by wildfire remain concerned about the future forest landscape of these areas. We analyzed post-fire pollen samples from unburned and severely burned sub-boreal spruce stands in north-central British Columbia four years after a major wildfire. We used pollen traps to measure the occurrence and abundance of pollen types from four important plant families: Asteraceae, Ericaceae, Onagraceae, and Pinaceae families, to address specific concerns of the First Nation communities with territories overlapping the Shovel Lake wildfire burned area. Pinaceae pollen was found across all traps and was observed as the most dominant pollen type at all study sites, while pollen belonging to other families was found less frequently. No significant differences in pollen occurrence or abundance were found between burn severities, despite differences in the plant communities; however, plant and pollen abundance were found to be positively correlated to one another. These results may indicate that, as previously noted in other conifer-dominated forests, openings of the forest landscape by wildfire may facilitate rather than hinder pollen movements. Understory species should be studied in more detail as the effect of wildfire on pollen transport may vary between taxa and pollination syndromes. Full article
