GRASSROOTS INPUT TO ENVIRONMENTAL DEBATES
Going with the flow of the Dunham River
Upper Dunham River water catchment
As many landscape-rehabilitation and landscape-revitalisation processes do not immediately contribute to any commercial activity these sort of issues can only be addressed once either the threat of flooding becomes apparent to down-stream communities or if society begins to place a monitory value on healthy functional landscapes.
|Flying Fox Yard: Physical infrastructure is threatened by both erosion and flooding whilst the source of reliable water is sanding up.||Gully-erosion (marked by the mowed track around the perimeter – bottom left hand side of the picture above) has not progressed in recent years. This is because the choking up of drainage lines immediately down-stream has slowed the draining of floodwaters; actual gullies are under water during a flood and no further local erosion occurs.|
|In most years an eroding Western riverbank makes room for the wet-season flow.|
|“Looking upstream”: A vast and rugged setting can easily distract us from noticing subtle (and sometimes not so subtle) changes in our landscapes.||Statements like “fire is natural” can also be a distraction.|
|A human made wetland habitat being subjected to fire: in this case a natural physical force/disturbance unleashed by humans. What is the net effect on biodiversity of these prevailing practices?||No doubt “time” will be the fairest judge of the benefits of current landscape management.|
