Statistical analysis

Results and Discussion

Net mineralization increases as distance from swales increases (data trend)

Flood plain positions had higher ammonium concentrations than the channel and bank (p=0.0159)

Swales had higher proportion of natives than ephemeral ponds (p=0.0415)

Swales had lower exotic richness than permanent ponds (p=0.0645)

Native richness increases as distance increases from ephemeral ponds (data trend)

Exotic richness and proportions decrease as distance from permanent ponds increases(data trend)
