I really am struggling with a game that adds resources that will be later used for building, collision detection is all messed up what is a better alternative if (isTouching(Survivor.class) && (Greenfoot.isKeyDown("space"))) { woodCounter+= 1; getWorld().showText("Wood:" + woodCounter, 100, 100); }

So, I presume you only what it to increase by one for each time the "space" is pressed. You will need a boolean field to track the state of the "space" key: 
// add field
private boolean spaceDown;

// in code
if (spaceDown != Greenfoot.isKeyDown("space"))
{
    spaceDown = !spaceDown;
    if (spaceDown && isTouching(Survivor.class))
    {
        woodCounter++;
        getWorld().showText("Wood:" + woodCounter, 100, 100);
    }
}
Check the size of the image assigned to the Survivor object and that of 'this' object.
