Narrative:

At approximately 15 miles from alpine airport I contacted dispatch to attempt to get a helibase frequency; as my resource order did not include any communication details. Dispatch gave me a contact frequency for [the helibase]; but there was no response on this frequency. I contacted dispatch again and asked if they would be up on unicom and they said they would. At ten miles I did a standard report of my position and intent. At five miles I reported again; calling alpine radio. They responded immediately. I asked for landing preferences; and if anyone was available for parking instructions. Another [helicopter]; aircraft Y called reporting his position and calling for #2 to the airport following my aircraft. I reported a 1 mile final to the ramp. Alpine radio gave me final landing instruction. On short final a small single engine yellow cub type aircraft appeared. I slowed my helicopter and turned to avoid the landing aircraft. Neither myself nor the aircraft Y pilot or copilot had seen the yellow cub due to the color of the aircraft in the surrounding brown terrain. The airport manager said that he had no knowledge of him being in the area; even though he had a radio. The pilot from aircraft Y did not hear the report of entry into the pattern; downwind; base or final. Neither did the individuals that were operating the radio at the airport. I spoke to the pilot after landing; they felt that the separation was adequate; and that more frequent reporting in this high fire traffic environment would be a wise thing. They stated that they're is relatively new to the aviation environment.
