The Oak on Tanner Road Turns Fifty

Tanner Road was not a street that did things together. It had argued about parking for eleven years, about bins for nine and about a hedge for so long that nobody could remember which side had started it. People nodded at each other in the mornings in the way that neighbours do when they have silently agreed never to discuss the hedge again.

The oak stood outside number twelve, halfway along, where the pavement bulged a little to make room for its roots. It had always been there, as far as anyone knew. Children climbed its lowest branch and were told off for it. Cats sat under it in summer. Cars parked in its shade and complained about its acorns in autumn, which the oak did not seem to mind.

Then Mrs Adeyemi at number twelve found a letter in a box of her late father's papers. It was from the council, dated a spring fifty years earlier, confirming that a young oak would be planted outside the house at the request of the residents. At the bottom, in blue ink, her father had written a date and the words planted today, rained all afternoon, worth it.

She did not tell anyone. She simply bought a birthday card, wrote happy fiftieth on it and pinned it to the trunk with a drawing pin. By the next evening there were four more cards. Someone had added bunting. Someone else, who had not spoken to the people across the road since the hedge, had left a small plate of biscuits on the low wall with a note that said for anyone.

The party happened the following Saturday, although nobody quite organised it. People brought folding chairs and cake and a speaker that played the wrong kind of music. The children were allowed on the lowest branch for once. Two men who had not agreed about parking in over a decade spent an hour discussing how tall the tree might be, and eventually fetched a tape measure, a ladder and a lot of opinions.

The hedge was mentioned only once, and briefly, and everybody laughed. By the time the street lamps came on, the cards had been taken down and put in a biscuit tin, and a list had gone round for next year. The oak, for its part, dropped one acorn onto the cake table, which everyone agreed counted as a speech.

The story is made up, but the tree is not far from the truth. Many street trees were planted at the request of residents, and councils and local history groups often hold records of when. A tree's age can be counted exactly from the rings inside its trunk, one for each growing season, and foresters can check a living tree without harming it by using a hollow drill called an increment borer, which pulls out a core about as thin as a pencil. Research on towns and cities has also linked streets with more trees to cooler summer pavements, which is one more quiet reason people end up gathering in their shade.
