You not only need to look up the tree specie but see how it has been tended and what variety it may be. Your soils may vary and a lot of park varieties are more upswept with a lesser spread for parks, etc. than wild varieties. A lot of routes require trees to be cut back for taller vehicles and contractors/authorities often pollard trees – companies too to maintain power or communications. 13 agencies can dig my road, with permission, each employing various contractors. They may all affect trees and their growth, even existence. The local and state authority will employ tree folk (as it were) and interviewing them may be your best bet. Don’t forget to do your homework first re existing reports and leaflets on paper or online, check out individuals you are going to interview and measure sample treesin different locations. Trees were often planted after founding areas, after wars, for the centenary or millennium, etc. Check future plans and policies.
This is St. Mary’s Church, Prittlewell. A tomb of a Saxon prince was discovered nearby from the 7th century but the church is not too old. It fronts the main route into town where all the trees are tended for traffic management. No large vehicles are expected to go down the side of the church so the trees, of different ages, are untouched. Cabs park up to the birch at times but any truck coming down there would have to watch out. Yews by the path to the church are regularly clipped back for access both along the path and in the grassy churchyard behind them. They are unlikely to spread until the church crumbles. (Yews live 3000 years before rotting and growing anew for another 3000 years.)
