�It appears to me that the beauty of our river, our parklands, is being reduced. In fact, we can�t see it,� Cr Brett Pollock said.
At last week�s meeting, Cr Pollock successfully proposed a review of council-directed bushcare programs run by volunteers to see if they were getting in the way of residents� views and making parks smaller.
He and Cr Wesley Davies recently walked along the river remembering greater views in their childhoods.
�People are becoming alarmed by these open spaces being reduced rapidly by these over-plantings,� Cr Pollock said.
The council�s bushcare budget is about 10 per cent of about $1.5 million it spends on mowing parks each year.
Friends of Mosman Park Bushland convenor Sue Conlan said a review would be �selfish�.
Ms Conlan said the council�s South Mosman Park Bush Management Plan, which had been created using Department of Parks and Wildlife flora and fauna surveys to create corridors so wildlife could move through the suburb, guided volunteers� work.
�Mosman Park also has the only community of the plant winged boronia left in Perth, and we�re trying to support that by planting other plants around it, so that�s probably what�s been seen in the parks,� she said.
Planting stops riverside erosion, provides habitat, restores vegetation cut down after colonisation and stops garden fertiliser run-off entering the river.
�Whenever we are down by the river planting each Friday, we always have people saying, �I love coming down and seeing what you�ve done here�,� Ms Conlan said.
Last spring, planting created enough new habitat to attract the rare blue wren after many years without the bird in Mosman Park.
Councillors will get a report on parks and planting this month.
