This lone survivor caught the public's imagination as a symbol of hope and was widely reported upon by newspapers worldwide.[13] Also, since one tree survived, the official designation as a "Place of Scenic Beauty" was not revoked. The lone surviving pine died in December 2012 due to seawater contamination of the surrounding soil. Disaster recovery work began in December 2013 with the building of a new sea wall and restoration of the beach, which had been buried in meters of silt. Cleanup efforts were hampered by fears that the wood of the fallen pines had been contaminated by radiation effects from the Fukushima Daiichi nuclear disaster. Tree planting events were held in 2017 and 2018, during which time 2500 pine seedlings were planted by volunteers. The area is now part of the Sanriku Fukkō National Park.[citation needed]
