The authors investigate the throughput of an ALOHA land mobile satellite network operating in a vegetative shadowing environment. The fading statistic is represented by a lognormal probability density function which is incorporated in the throughput analysis. Both slotted and unslotted ALOHA protocols are considered. With the use of numerical analysis, it is shown that vegetative shadowing or lognormal shadowing improves the throughput considerably by reducing the mutual packet interference and thus enhanced the capture probability of a shared satellite receiver.<>
