Temperate and Boreal Forests Compared
How mid-latitude temperate forests and northern boreal forests differ in climate, dominant trees, soils, seasonal rhythm and the disturbances that shape them.
Forest Types and Biology
Temperate and Boreal Forests
Forests of the mid and high latitudes and how they change over time.
Canopy Gaps and How Forests Renew Themselves
How a fallen tree opens a patch of light in the canopy, which seedlings take advantage, and why gaps make forests a patchwork of different ages and species.
Conifer Forests: Needles, Cones and Cold
Why needle leaves, cones and narrow crowns suit conifers in cold, dry or nutrient-poor places, and how conifer forests differ from broadleaf woods.
Deciduous Forests and the Seasonal Cycle
How broadleaf forests prepare for winter, drop their leaves, rest through dormancy and burst back into growth each spring, and what that means for the life beneath.
Forest Succession from Clearing to Mature Stand
The typical stages by which a cleared or burned site returns to forest, from first colonizers through young stands to mature woodland, and why paths vary.
Mediterranean Woodlands and Dry Summers
How oak and pine woodlands cope with hot, dry summers and mild wet winters, why fire is part of their story, and how people have shaped them for thousands of years.
Mixed Forests and Why Species Mixtures Matter
What mixed stands are, how combining tree species can affect resilience, growth and wildlife, and why the benefits depend on which species are paired.
Old-Growth Forests and What Makes Them Distinct
The structural features that separate very old forests from younger stands, including big trees, dead wood, layered canopies and slow soils, and why definitions vary.
Permafrost and the Boreal Forest Edge
How permanently frozen ground shapes northern forests, why trees grow slowly on it, and what permafrost thaw could change for roots, water, fire and carbon.
Savanna Woodlands and Open Forests
How savannas and open woodlands mix scattered trees with grass, what keeps them from closing into forest, and how fire, grazing and rainfall hold the balance.
Treelines in the Mountains and the Far North
What sets the upper and northern limit of tree growth, how treelines look on the ground, why they move slowly, and what warming may change.
