Letter From Estela Romero: The Long Wait (for visitors) is Over!
Estela Romero reports on monarch activity at the El Rosario and Sierra Chincua Sanctuaries. She writes, "At the El Rosario and Sierra Chincua Sanctuaries, monarch colonies are now well defined and dense. Big clusters can be clearly identified at various locations viewable by visitors. Our temperature conditions continue to be very concerning, ranging from 23-25 Centigrade in the shade. We fear that ideal levels of humidity will disappear."
