Santiago del Teide Ayuntamiento is carrying out a survey to try to develop its niche tourism markets, specifically ecotourism (focusing on nature and the environment, and smaller local businesses, conservation, sustainability, etc). By definition, this is a survey they are carrying out among tourists, but I imagine that part-time residents more than qualify as well, and the municipality has its fair share of those! The survey questionnaire is HERE and is in English as well as Spanish: just click the Submit button on the bottom of the form to send your answers in.
