# University team walks an old survey grid to see what grew back

> A paper from the School of Emergent Priorities and the School of Underlying Conditions returns to an abandoned seismic survey grid and finds that how each line was cut still decides whether it can be seen.

Two of the University's schools shared a field season this year, and the paper
that has come of it is published today. _Thirty-One Years on the Cut Line: Shrub
Regrowth across an Abandoned Seismic Survey Grid in a Semi-Arid Shrubland_ is
the work of Ms Ylva Ogunbanjo, Doctoral Candidate in the School of Emergent
Priorities, and Dr Brynjar Obiora, Senior Research Fellow in the School of
Underlying Conditions.

The survey in question was cut in a single dry season and given up without a
well being drilled. The authors found that lines made with the bulldozer's blade
raised had returned to a median 0.84 of the shrub cover beside them, and lines
made with the blade lowered to 0.37. The width of a line made almost no
difference. The banks of spoil left along the edges now carry more shrub than
the country that was never touched.

The team located each line from the original survey markers, set a measured
length along it and another alongside, and brought ground readings together with
five rounds of aerial photography into a single integrated account of recovery
across the grid.

The University regards the paper as a considered instance of what its schools
can do in one another's company. "A doctoral candidate asked whether I had a
penetrometer and a free month," said Dr Obiora. "I had one of the two, and the
School was good enough to find the other."
