Paleoecological and historical data as an important tool in ecosystem management

Area of Science:

• Forestry and Paleoecology
• Environmental History
• Disturbance Ecology

Background:

• Most European forest fires are human-caused, with extreme droughts exacerbating risk, particularly in Central Europe.
• Catastrophic fire events are under-recognized in Central European Lowlands (CEL), despite extensive forest complexes.
• Large coniferous monocultures in CEL are highly susceptible to fires and other disturbances, necessitating historical context for management.

Purpose of the Study:

• To document the effects of past land management on modern disturbance regimes in the Tuchola Pinewoods (TP), northern Poland.
• To utilize paleoecological data, historical documents, and cartographic materials to understand long-term forest dynamics.
• To present a protocol for forest managers to integrate long-term paleoecological records into their practices.

Main Methods:

• Paleoecological investigations of past environmental conditions.
• Analysis of historical documents and cartographic materials.
• Case study approach focusing on the Tuchola Pinewoods (TP).

Main Results:

• Over the past 300 years, TP experienced disastrous fires, windfalls, and insect outbreaks.
• An 18th-century management shift to Prussian/German administration transformed mixed forests into Scots pine monocultures for economic gain.
• This administrative decision created an ecosystem highly vulnerable to disturbances, including fires.

Conclusions:

• Past land management decisions, particularly the creation of Scots pine monocultures, significantly increased ecosystem susceptibility to disturbances.
• Understanding historical forest management is crucial for assessing current fire risks and their impact on biodiversity, water management, and climate change mitigation.
• Developing a dialogue between scientists and managers is essential for informed forest management practices under projected climate change scenarios.
