Trees as recultivation or fitopurification instrument and usage of municipal residues (wastewater sludge and wood ash) for

“rehabilitation” of tree stands

Деревья как инструмент рекультивации и фитоочищения и использование муниципальных остатков (осадки сточных вод и

пепла древесины) для «реабилитации» рощи.

Trees on roadsidesSmall trees and bushes along

highways and country roads:

absorb dust and small particles;

slow, absorb, and clean water that runs off the highway, resulting in reduced soil erosion, flood control and cleaner water supplies;

serve as living snow fences, catching snow rather than letting it drift across travel lanes;

provide important pollinator habitat.

Transportation enhancements help by: minimizing necessary roadside

maintenance;

supporting trail construction and tourism;

employing landscaping professionals and County Roadside Managers.

supporting farmers who cultivate and sell plant material.

Resources to extend biomass production (Rancane, Makovskis, Lazdina, Daugaviete, Gūtmane, Berzins. 2014, Agronomy research)

The combined growing of trees and grasses on the

same area, give

possibility to save costs and earn an incomes in

first years, which cover starting expenses.

Reed canary grass,

festulolium, and galega could be successfully

grown for biomass and

seed production between trees rows in the

agroforestry system in Latvia. The use of

different bio-energy and

municipal waste products as fertilisers in general

provided higher biomass

and seed yields.
