question: In what year were an estimated 52,000 tons of rosewood lumber harvested before the situation improved in Morojejy?
context: Madagascar's northeastern rain forests are severely threatened by illegal logging of precious hardwood, which not only dries out the forest (making it susceptible to fire), introduces invasive species, degrades habitat, and reduces genetic diversity, but also violates local taboos and traditions.  Additional species, such as species of Dombeya, are typically cut to make rafts for floating the heavier hardwoods down rivers and out of the parks.  Rosewood trees are cut into multiple logs for easier transport, and five or more high-buoyancy trees are cut per hardwood log.  To tie the rafts together, the loggers cut thousands of lianas or vines, which are used by 75% of the forest fauna as avenues for moving around in the canopy.  The logging activities are labor-intensive and dangerous.  The labor employs the impoverished local population, but the officials who facilitate the process primarily benefit.
  In 2005, illegal logging of rosewood was reported to have occurred more than 20 times. In 2007 at the port cities of Vohémar, Antalaha, and Toamasina, authorities confiscated thousands of logs valued at millions of dollars (US$).  Some of this material was reportedly logged from eastern and northeastern parts of the park.  At the start of the Malagasy political crisis in March 2009, thousands of woodcutters intensely logged precious hardwoods for six to eight weeks in the SAVA Region.  An estimated 52,000 tons of rosewood lumber, or nearly 100,000 trees, were logged that year, with one-third of the total coming from Marojejy National Park and the remainder from nearby Masoala National Park.  As a result, the park was closed briefly, but reopened in May 2009.  In 2010, the situation improved in Marojejy, but illegal logging intensified in Masoala and the Makira Protected Area.Illegal logging has been facilitated by insufficient governance, unclear forest regulation, and undermined judicial control while the exportation of the acquired logs (in 1992, 2006, and 2009–2010) has been permitted by government decrees that either precede elections or are issued during periods of political instability.  The trade is organized and operated by high-ranking officials and influential businessmen.  Additionally, the trade in Malagasy rosewood is not regulated under the Convention on International Trade in Endangered Species (CITES).
