Ongoing Projects:

State Project:

The Maryland Department of Natural Resources (DNR) runs a volunteer water quality monitoring program: Stream Waders.  See Stream Waders, Md. Dep’t of Nat. Resources,  last visited Apr. 10, 2017).  We were unable to find statutory authority for the program, which DNR appears to have created on its own initiative.

Place of Collection:

Criminal Liability for Trespass Despite Lack of Notice:

In order for entry upon property to constitute trespass, the property must either be “planted with a crop or orchard” or be “posted conspicuously against trespass” by signs or paint marks on trees or posts at road entrances and “adjacent to public roadways, public waterways, and other land adjoining the property.”  Md. Code Ann., Crim. Law §§ 6-402; 6-406(b).

Drone Laws:


“Only the State may enact a law or take any other action to prohibit, restrict, or regulate the testing or operation of unmanned aircraft systems in the State.”  Md. Code Ann., Econ. Dev § 14-301.


Encourages Depart of Business and Economic Development, University of Maryland, Department of Transportation, and other “interested groups” to work together to evaluate benefits and risks of drones to develop further law/policy in Maryland regarding drones.

Use of Information:

Although incomplete, our research has not found any provisions relating to the use of information collected by citizens in enforcement or administrative/legislative actions.

Evidentiary Standards:

Pleading a Claim:

Requires certification that “there is good ground to support” the claim.  Md. R. Evid. 1-311.
