Cheers. Seem to be very tough to fell, worked the chainsaw hard lol
Edit: left that one up, but ones in middle section were rotten so had to come down.
Not the best time of year to be felling as the sap will be up. Also, try not to cut too near the base as this will knock 10 bells out the chain and will go blunt very quickly.
Almost certainly a Prunus of some sort (cherry/plum). Looks more like one of the purely ornamental types rather than a fruiter. Don't leave the logs stacked on bare earth - they might take root!
