Landing Runway 14 at LKP. While stabilized on final on PAPI 3.5 degree glide path; it 'felt' low. After safely landing and discussing with FBO personnel; they commented 'if you stay on the PAPI glide path; you might get some pine needles in your wheel well. The PAPI has not been calibrated in a few years and the trees have only grown taller.'  Additionally; no 'official' wind information is available and would be very helpful for high performance aircraft operating at this location. Obstacle clearance while on PAPI needs to be evaluated. As a Company; I believe we need to evaluate whether operations in/out of LKP fall within a prudent safety margin given the airfield configuration and the nearby location of SLK.
The pilot of a small jet transport felt low while flying the VGSI slope to LKP Runway 14 and was told after landing that trees had grown up to just below the 3.5 degree visual path.
