The flag of the Ministry of Environment and Natural Resources has had at least two flags, both of the same basic design showing the Ministry's logo centered on a white field. As the logo has changed, so has the flag. The current iteration of the logo shows a green tree growing upward from the Ministry's name in black capital letters in three lines: "MINISTERIO DE," "MEDIO AMBIENTE Y," and "RECURSOS NATURALES." Photos of this flag can be seen online here and here, both from 2016. Randy Young, 29 April 2016
The Ministerio de Medio Ambiente y Recursos Naturales (Ministry of Environment and Natural Resources) is one of the cabinet ministries of the Dominican Republic government. According to the Ministry's website, "The Ministry of Environment and Natural Resources is the agency responsible for designing, executing and overseeing national policy on environment and natural resources, and promoting and stimulating activities of preservation, protection, restoration and sustainable use." The Ministry was officially formed in 2000 through Law No. 64-00, transferring the conservation and protection mission from the Ministry of Agriculture to the new State Secretariat of Environment and Natural Resources (Secretaría de Estado de Medio Ambiente y Recursos Naturales), which was renamed as a Ministry in 2010. The Ministry, though, continues to trace its lineage to 1844 with the founding of the Republic and Decree No. 2295 that first ordered conservation of the new country's forests.

The previous version of the logo – and therefore the flag – was very similar, differing only the display of the Ministry's name. In that version, the name was again displayed in three lines of black capital letters, but the margins of the wording were justified so that beginning and ending letters of each line were aligned vertically: "MINISTERIO," "DE MEDIO AMBIENTE," "Y RECURSOS NATURALES." Photos of this flag, from 2013 and 2015, can be seen online at here (flag on the far left), here, and here. Randy Young, 29 April 2016
While I have found no photographic evidence yet, I would venture to guess that the flag of the State Secretariat for Environment and Natural Resources likely followed the pattern of other ministries' flags when they too were state secretariats – the secretariat's logo centered on a white field. However, I have no evidence yet to back up that theory. Randy Young, 29 April 2016
