Black Poplar
Populus nigra
A majestic deciduous tree reaching heights of up to 30 meters, characterized by its deeply furrowed dark bark and distinctive burrs. As a pioneer species, it prefers moist, nutrient-rich gravel and sand soils within dynamic river floodplains. The pure wild form has become rare in Europe due to hybridization with the Canadian Poplar and the extensive loss of natural flooding habitats.
Details
Oxygen production
High, due to rapid growth rate and large leaf surface area.
Habitat function
Nesting site for raptors, food source for butterfly larvae, provider of large woody debris for aquatic organisms.
Nutrient uptake
Effective uptake of nitrates and phosphates from the floodplain soil.
Food source for
Puss moth, Poplar longhorn beetle, various leaf beetle species.
Human use
Wood for crates, matches, and carvings; bud extracts used in herbal medicine (poplar ointment).
Ecology
Ecological role
Key pioneer species that stabilizes riverbanks and provides habitat for numerous specialized insects and birds.
Natural predators
Various phytophagous insects (e.g., poplar leaf beetle), fungi such as poplar rust.
Competitor species
Populus x canadensis (Hybrid poplar), White willow (in early successional stages).
Ecosystem service
Flood protection through bank stabilization, carbon sequestration, purification of shallow groundwater.
Threats
Hybridization with cultivated poplars, loss of dynamic floodplains due to river engineering, lowering of groundwater levels.
Scientific profile
Profile
Protection & threats
Main threats
Introgression (hybridization) by hybrid poplars (Populus x canadensis), loss of primary habitats due to river regulation and lack of natural dynamics.
