Високите дървета включват първите посадени дървета, както и бавно растящи видове. Растящи бурно и фиксиращи азота в почвата, тези растения-пионери бързо овладяват навесния слой, докато развиват плодородието на почвата, задържането на водата, осигуряват естествена среда за диви животни, осигурявайки дървесенматериал. Бавно растящите ни видове са основно орехови дървета. 

Robinia pseudoacacia

Black Locust. Nitrogen-fixing, pioneer species. Fast growing, beautiful tree. The timber is rot-resistant making it ideal for fence posts and outdoor furniture. A good coppice tree. Flowers in June with a hedonistic scent, very attractive to bees. Flowers are eaten raw or made into a sweet drink. Very easy to grow from seed. Suckers freely.
Hardiness zone: 4
Seed treatment: SC

Alnus cordata

Italian Alder. Nitrogen-fixing, shelter belt tree. Provides habitat for wildlife. Thrives in damp soils with poor drainage but can tolerate dry conditions more than other Alnus species, making it an exceptional temperate, nitrogen-fixing species for drier climates. Does not require full-sun. Good tree for north-facing slopes. Great coppice species. Wood useful for small construction projects. Can be tapped for an edible sap. Flowers provide nectar for bees in March.
Hardiness zone: 6
Seed treatment: CS8

Paulownia tomentosa

Empress Tree. Nitrogen-fixing, pioneer species. Very fast-growing tree. Rot-resistant wood ideal for fence posts, tipi poles and light construction. Fast growth and large leaves provide high yield of bio-mass for mulching and compost. Protein-rich leaves can be used for animal fodder. Beautiful purple flower clusters in May provide an abundant nectar source for bees. Coppices well. Very easy to propagate from softwood and root cuttings. Prefers fertile, well-drained soil. Can be invasive.
Hardiness zone: 5

Gleditsia triacanthos

Honey Locust. A striking tree, often kept away from public places due to its formidable thorns. A thin canopy comes into leaf late and loses leaves early, ideal for a woodland garden. The wood is tough and rot-resistant. Seeds can be roasted and used as a coffee substitute. A sweet pulp from the seedpods can be eaten raw or used as a sweetener. Flowers in July provide nectar for insects.
