Conifer Rows on Slopes Do Not Dam Groundwater

Question: Does a line of conifers on a hillside block/dam subsurface water flow?

Answer: No

• Roots are discrete, not a continuous barrier.
• Most conifer roots in top 2 ft (except pine taproot).
• Water flows through soil matrix around roots.
• No "dam" effect—roots occupy <5% of soil volume.

Vegetation uses water (transpiration) but does not physically block lateral flow in any meaningful way. The premise confuses root occupancy with hydraulic barrier.
