Urban forestry can be an important tool for stormwater management as trees intercept rainwater in the canopy, and can slow down, filter and pump water back into the atmosphere via their roots. [7] [8] Other benefits include noise control, traffic control, and glare and reflection control. [9]
Tree inventories focus on the attributes of individual trees, as compared to a forest inventory which seek to assess timber attributes on forest stands. Information such as how many street trees there are, what their species is, and their condition is gathered. A community forest cannot be effectively managed unless its condition is known.
Trees planted in municipal areas are subject to removal as preferences change. Urban reforestation efforts compete for money and urban land that could be used for other purposes. For example, effort placed in planting new trees can take away from maintenance of already established trees. [ 11 ]
Neighborhoods with fewer trees can be up to 20 degrees hotter than areas with more trees and green space. Trees can help reduce flash floods and runoff during storms. And they convert carbon ...
The forest is a natural system that can supply different products and services. Forests supply water, mitigate climate change, provide habitats for wildlife including many pollinators which are essential for sustainable food production, provide timber and fuelwood, serve as a source of non-wood forest products including food and medicine, and contribute to rural livelihoods.
Throughout their lifespan, trees continue to sequester carbon, storing atmospheric CO 2 long-term. [27] Sustainable forest management, afforestation, reforestation are therefore important contributions to climate change mitigation. An important consideration in such efforts is that forests can turn from sinks to carbon sources.
Remedial strategies include: more careful waste management, statutory control of overfishing by adoption of sustainable fishing practices and the use of environmentally sensitive and sustainable aquaculture and fish farming, reduction of fossil fuel emissions and restoration of coastal and other marine habitats.

The Earth’s trees absorb more than 7 billion metric tons of carbon dioxide — about a fifth of what the world lets out into its atmosphere — and release it back as oxygen or bind it into ...
