This is below the minimum static RPM. If by "take off" you mean when the wheels left the ground, then the problem is even worse! Static RPM is the full throttle RPM measured at a dead stop. By the time you reach takeoff speed your RPM should ba a couple 'hundred RPM higher than your static reading. If your plane can't make the minimum, you owe it to yourself to figure out why before you start your take off roll. Most common reason, other than faulty tach, is low engine power, which can lead to the problems you described, i.e. extended take off roll and brushes with trees. (BTW, if you cannot make static RPM as spelled out in the TCDS then your plane does not meet the certification requirements and is unairworthy, in this case with good reason...)
