Only thing I w outdoor suggest, write to San Javier Town Hall, not sure if they have any powers over rat colonies or indeed obstructive trees.
Maybe worth asking Resortalia to pass your comments on to the EUCC Board for pressure from them, but don't get your hopes up.
Get the nearby Communities and Resortaliabinvolved over rat problem, they can place traps on their land near to golf course.
Post pictures on Roda & Around on Facebook others may also join in with pressure.
