This plugin allows the server owner to control how many entities can be spawned in a chunk (or a region such as a plot if you're using a region management plugin).

If your server faces a problem with players spawning too many entities (mobs/animals), you can control the spawning with this plugin.

You can set the maximum spawn number per chunk/plot for each entity type.

If you have a region management plugin such as:

• ASkyBlock,
  
• Factions,
  
• FactionsUUID,
  
• FEUDAL (since I don't have an access to this plugin, i haven't tested it but it should work.),
  
• GriefPrevention,
  
• Kingdoms+,
  
• LegacyFactions,
  
• NovaGuilds,
• PlotMe,
• PlotSquared, (PlotSquared v3 and PlotSquared v4)
• Plotz,
• PreciousStones,
  
• RedProtect,
• Residence (NOTE: as of Mar/2017, Residence depends on Kingdoms+ plugin),
• Towny,
  
• uSkyBlock
• WorldGuard (ENTRY region flag) (6.x and above)

you can use the entity limit per plot/region/etc.
You can find the types of entities at https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/EntityType.html

• /ectl | /ectl help : displays the help menu
